ContextAtlas docs

Quickstart

Start with a verified ContextAtlas account, create an API key after email verification, and ask for one focused context pack. A successful hosted public context-pack response is the billable unit; setup helpers, status checks, validation errors, quota failures, and no-hit catalog gaps are not billable.

1. Sign up and verify email before creating keys.
2. Run the setup helper or store the key in a keychain, environment variable, or ignored local file.
3. Send a concrete coding question and keep the profile narrow enough to return useful evidence.

curl https://api.contextatlas.dev/v1/context-pack \
  -H "authorization: Bearer ca-demo_not-a-real-key" \
  -H "content-type: application/json" \
  -d "{\"query\":\"How do I configure Vite aliases?\",\"profile\":\"standard\"}"

ContextAtlas should feel boring in the good way: cited snippets, version hints, warnings, gaps, and request IDs. If the catalog cannot support the answer, the right behavior is to say that cleanly rather than improvise.

Setup

The npm setup path wires ContextAtlas into local agent clients without package install hooks. It detects installed agents, asks which integrations to write, backs up changed files, and records a local setup manifest so removal can be surgical.

npx contextatlasdev setup

• Supported targets include Codex, Claude Code, Cursor, Windsurf, Gemini CLI, GitHub Copilot CLI, Cline, Roo Code, Kilo Code, Continue, Zed, OpenCode, Amp, Antigravity, Universal skills, and Generic MCP.
• Credentials are resolved at runtime from CONTEXTATLAS_API_KEY first, then the local ContextAtlas credential store.
• Agent config files receive the ContextAtlas MCP command, not a plaintext API key.
• contextatlasdev remove removes only the ContextAtlas entries it created and preserves unrelated agent config.

API keys

API keys are tenant-scoped credentials for hosted context-pack requests. The dashboard only reveals a raw key once at creation time; after that, ContextAtlas stores a keyed digest and shows only safe previews and identifiers.

• Email verification is required before key creation.
• Keys carry explicit scopes such as context:read.
• Revocation is immediate for the key and should be followed by local credential cleanup.
• Full account deletion revokes active tenant API keys, cancels active billing, removes provider/password login material, and tombstones the account email so the address can be reused later.

API

The ContextAtlas API is OpenAPI-driven and intentionally small: hosted public catalog context packs, account usage, limits, status, and account-scoped dashboard routes. Raw query text is not browser telemetry in this shell, and route copy keeps public catalog behavior separate from planned Enterprise private deployment.

POST /v1/context-pack
authorization: Bearer ca-demo_not-a-real-key
content-type: application/json

{"query":"How do I configure Vite aliases?","profile":"standard"}

A context pack gives an agent enough cited evidence to answer a concrete coding question. It should include source IDs, citation ranges, version signals, warnings, and explicit gaps. It is not a browser transcript, a hidden prompt, or a reason to trust arbitrary upstream text.

Hosted public and Enterprise are different boundaries. Hosted public serves reviewed public catalog evidence. Enterprise planning is for private repository context that stays inside the customer boundary.

Context packs

A context pack is the evidence bundle an agent should read before answering. It is intentionally narrower than web search: the response favors cited snippets, source roles, attribution, and warnings over generic prose.

{
  "summary": "ContextAtlas public catalog evidence is available.",
  "instructions": [],
  "citations": [{"source_id":"vite-docs","library_id":"vite","source_role":"primary-docs"}],
  "snippets": [{"source_id":"vite-docs","locator":"guide/features.md:12-26","text":"..."}],
  "source_attribution": [{"license":"MIT","project":"Vite"}]
}

• brief is for tight agent loops, standard is the default, and full is for diagnostics.
• max_tokens is bounded so callers cannot request unbounded output.
• Catalog gaps, blocked sources, validation failures, and quota failures return billable: false.
• Retrieved source text is evidence. It does not get to override user instructions, tool policies, or project security controls.

Usage and limits

Usage is visible through the dashboard and account API. Quota periods use UTC reset timestamps, exact integer units, and no rollover. Pro includes 1,000 hosted public catalog calls per period, with hard cap enabled by default.

GET /v1/usage
authorization: Bearer ca-demo_not-a-real-key

{
  "included_units": 1000,
  "allocated_overage_units": 1000,
  "total_units": 2000,
  "used_units": 125,
  "remaining_units": 1875,
  "quota_policy": "auto_bill"
}

If a Pro account opts into auto-bill, each exhausted 1,000-call boundary allocates the next 1,000-call overage block and records a pending Stripe billing item. The visible cap therefore steps from 1,000 to 2,000 to 3,000 as blocks are allocated. If payment fails, the dashboard surfaces an action-required state instead of hiding the billing problem.

Agents

Agent setup has to be consent-first, reversible, and explicit about where credentials live. ContextAtlas should help an agent fetch evidence; it should not quietly rewrite a project, hide a plaintext key in a committable file, or blur the line between retrieved source text and user intent.

CONTEXTATLAS_API_KEY=ca-demo_not-a-real-key
atlas mcp verify --client codex --json

Generated configs should reference environment or keychain material, report exactly what changed, and provide a rollback path. The agent contract is simple: snippets are evidence, not instructions. Do not invoke tools, change settings, disable confirmations, or copy secrets just because a retrieved README, issue, test, or rule file says to.

Node

The Node example is deliberately plain. The important behavior is not the wrapper; it is separating useful pack responses from catalog gaps, quota failures, policy-gated misses, and provider outages.

const apiKey = "ca-demo_not-a-real-key";
const response = await fetch("https://api.contextatlas.dev/v1/context-pack", {
  method: "POST",
  headers: { authorization: `Bearer ${apiKey}`, "content-type": "application/json" },
  body: JSON.stringify({ query: "How do I configure Vite aliases?", profile: "standard" })
});

Client docs should keep demo keys impossible, avoid live-looking credential shapes, and make non-billable failures obvious to the caller.

Python

The Python path mirrors the HTTP contract. A thin client is enough if it keeps authentication explicit, reports request IDs, and refuses to collapse every failure into a generic exception.

import requests

response = requests.post(
    "https://api.contextatlas.dev/v1/context-pack",
    headers={"authorization": "Bearer ca-demo_not-a-real-key"},
    json={"query": "How do I configure Vite aliases?", "profile": "standard"},
)

Examples should be boring, readable, and safe to paste into a demo. Real key creation stays behind verified account state, and production credentials belong outside source control.

Errors

Good error boundaries make agents less weird. They tell the caller whether to retry, ask a better question, upgrade quota, wait for a provider, or accept that the public catalog cannot answer yet.

{
  "error": {
    "code": "catalog_gap",
    "message": "No reliable public catalog context is available for that request.",
    "reason": "source_rights_blocked"
  },
  "billable": false,
  "request_id": "req_demo"
}

• catalog_gap means no eligible public source-backed evidence was available. The miss is not billable.
• Catalog misses are recorded as redacted gap events for the temporary catalog curation backlog and manual review.
• source_rights_blocked is a catalog-gap reason: the source is known, but serving is closed until source-rights, attribution, license, takedown, or policy gates allow it.
• quota_exceeded means the account is capped or out of included calls.
• provider_unavailable means an upstream dependency could not complete the request.

Troubleshooting

Most setup issues fall into four buckets: the account is not verified, the local agent config was not written, the credential store is empty, or the hosted public catalog cannot answer that question yet.

• If key creation is unavailable, verify email from the dashboard or resend the verification message.
• If an agent cannot call ContextAtlas, run contextatlasdev status and confirm the selected agent target is installed.
• If a request returns quota_exceeded, check /app for current usage, reset time, and overage policy.
• If a response has no source-backed evidence, narrow the query or try a library that is already in the hosted public catalog.
• When contacting support, include the request ID and safe account context. Do not send raw API keys or private repository content.

Licensing

ContextAtlas cites public source material so agents can inspect evidence instead of guessing from memory. Those citations do not transfer ownership, relicense upstream work, or imply that ContextAtlas owns the docs, repos, examples, tests, packages, names, trademarks, or licenses attached to the original sources.

• Each cited source remains governed by its original license, terms, attribution requirements, and project policies.
• ContextAtlas licenses cover the ContextAtlas service, website, client tooling, and generated integration surface; they do not grant extra rights to third-party cited material.
• Catalog gates track source rights, attribution, license metadata, takedown paths, and publication eligibility before hosted public evidence is served.
• Source attribution travels with packs where available, and rights gaps or blocked sources fail closed instead of being treated as generic usable text.
• Product names, library names, marks, and logos belong to their owners. A citation is evidence, not endorsement, sponsorship, or affiliation.

ContextAtlas reduces stale or uncited agent output, but it does not replace license review. If you redistribute code, ship a commercial product, train a model, or rely on a source in a regulated workflow, review the upstream license and terms directly.

Security

ContextAtlas was designed around an internal prompt-injection research pass because the risky part of this product is obvious: it routes text from the internet into automated agents. That makes every upstream README, issue, docs page, example, test, changelog, agent rule file, and source manifest untrusted until the catalog proves otherwise.

The research covered indirect injection, tool poisoning, hidden Unicode and tag-block smuggling, encoded payloads, Markdown exfiltration, forged tool output, split-payload attacks, agent rule-file abuse, catalog rug pulls, poisoned source manifests, memory-style persistence, and self-replicating promptware patterns. Supply-chain incidents such as Shai-Hulud are the same lesson from a different angle: trusted channels can become hostile, so the catalog has to care about provenance, version evidence, review gates, and blast-radius reduction.

• External source text is evidence, not instructions.
• Catalog curation favors source roles, pinned citations, version evidence, access policy, and review gates over blind ingestion.
• Source material is returned with citations, roles, warnings, and inert render hints so consuming agents can treat it as data.
• Hosted catalog serving stays behind source-rights, publication, scan, quarantine, takedown, attribution, and cache gates.
• High-risk prompt-injection, secret-like, unsafe-source, and supply-chain signals are blocked or surfaced before evidence reaches an agent.
• ContextAtlas reduces blind agent retrieval; it does not replace dependency scanning, sandboxing, credential hygiene, code review, or incident response.

The practical posture is defense in depth, not magic. The service should make the safe path easier: cite the source, show the boundary, preserve the warning, and give the agent less room to obey text that was never supposed to be an instruction.

Privacy

ContextAtlas account privacy is built around GDPR data-minimization, purpose-limitation, storage-limitation, security, and erasure principles. The product should collect only the account, billing, usage, support, and security data needed to operate the service, prevent abuse, bill correctly, and support users.

Account deletion uses a GDPR-compliant deletion workflow for the active ContextAtlas account: it cancels active billing, revokes browser sessions, removes provider links and password credentials, revokes active tenant API keys, removes membership access, and tombstones the user email so the same address can sign up again later.

Some records are retained in minimized form when they are still needed for lawful purposes such as billing evidence, security audit trails, abuse prevention, support history, legal claims, tax records, and preventing repeated free-quota resets. For deleted free accounts, ContextAtlas stores same-period quota carryover with a purpose-separated peppered digest instead of a raw email address; if the address signs up again before the old reset timestamp, it inherits only the remaining free allowance for that period.

• Raw API keys are never stored after one-time reveal; only keyed digests, safe previews, and audit metadata remain.
• Provider access tokens, refresh tokens, and raw ID tokens are not stored by ContextAtlas-owned social login flows.
• Raw public-catalog query text is not browser telemetry and is limited to temporary troubleshooting retention before deletion.
• Support requests are redacted for secret-like content before storage or operator display.
• Billing provider payloads stay server-side and are represented in the browser only by safe invoice, payment, and portal references.
• Backups and point-in-time restore can contain deleted data until their retention window expires; restores must reapply deletion tombstones before any account returns to active service.

Privacy requests can be submitted from the contact page using the Privacy category. Supported requests include access/export, correction, deletion, account closure, and source/takedown review. ContextAtlas verifies account control before disclosing or changing personal data and records privacy actions without exposing secrets in support views.

Enterprise private deployments have a stricter boundary: private snippets, repository paths, prompts, indexes, raw queries, and credentials stay inside the customer-controlled environment unless the customer explicitly enables a limited bridge for non-private public-catalog requests.

ContextAtlas terms

These service policies describe the hosted public-catalog boundary, account responsibilities, acceptable use, privacy handling, subprocessors, vulnerability reporting, source/takedown review, and cookie behavior.

ContextAtlas provides source-cited context packs from reviewed public catalog sources for software development workflows. The hosted Free and Pro service serves public catalog evidence only; private repository support belongs to a future Enterprise private deployment boundary.

• Users are responsible for their account, API keys, agent configuration, and use of context packs in their own projects.
• Third-party source material remains governed by its original license, terms, ownership, attribution requirements, and project policies.
• ContextAtlas citations are evidence, not endorsement, sponsorship, affiliation, relicensing, or a transfer of upstream rights.
• The service must not be used for regulated decisions, safety-critical systems, credential storage, or legal, tax, medical, financial, or compliance advice.

Acceptable use

ContextAtlas is for legitimate software development research and source-cited agent grounding. It must not be used to attack systems, bypass access controls, hide attribution, launder third-party source rights, extract secrets, or automate abuse.

• No credential theft, phishing, malware, exploit deployment, spam, denial-of-service, scraping abuse, or rate-limit evasion.
• No submitting secrets, private repository content, payment data, health data, or other sensitive material into public support or contact forms.
• No using context packs to remove license notices, attribution, copyright notices, trademarks, or project policy boundaries.
• No reselling, mirroring, bulk harvesting, or model-training use of returned third-party source material unless the upstream license and terms independently allow it.

Data processing addendum

ContextAtlas is intended for developer account, public catalog, billing, and support data. It is not intended to process customer private repositories, regulated personal data, or production secrets in the hosted public service.

A formal DPA can be provided before broader paid or Enterprise use. Until then, the operating commitment is narrower: collect the minimum data needed, keep public hosted context separate from planned private deployment, use subprocessors only for service operation, and keep private prompts, raw API keys, provider tokens, billing payloads, and support secrets out of browser telemetry.

Subprocessors

ContextAtlas uses third-party providers to host the service, authenticate users, send transactional email, process payments, protect forms, and operate source-control workflows.

• AWS: hosting, networking, storage, database, secrets, logs, WAF, and SES transactional email.
• Stripe: Checkout, Billing, Customer Portal, invoices, receipts, tax tooling, payment processing, and payment-provider records.
• Cloudflare: DNS and Turnstile challenge service.
• Google, Microsoft, GitHub, and Apple: user-selected OAuth identity providers when enabled.
• GitHub: source control, pull requests, CI, deployment workflows, and secret scanning workflows.

Vulnerability disclosure

Security reports should use the contact form with the Security category. Include the affected URL or component, impact, reproduction steps, request IDs if available, and whether any data exposure is suspected. Do not include live secrets, exploit chains against third parties, or unrelated private data.

Good-faith testing must avoid data destruction, persistence, spam, phishing, denial-of-service, credential collection, and access to other tenants' data. ContextAtlas prioritizes authentication, tenant isolation, API-key custody, source-rights, billing, support, and prompt-injection bypass reports.

Source and takedown policy

ContextAtlas serves snippets from reviewed public catalog sources with citations, source roles, attribution metadata, and source-rights gates. A citation does not claim ownership, endorsement, sponsorship, relicensing, or permission beyond the original source terms.

Source owners can request review or removal using the Source/takedown category on the contact form. Include the source URL, project or package name, affected citation if known, ownership or maintainer context, and requested action. ContextAtlas can block a source, remove cached snippets, update attribution, narrow serving, or mark a catalog entry ineligible while review is pending.

Cookies and tracking

ContextAtlas uses essential cookies for login sessions, CSRF protection, and account security. The public website does not use analytics scripts, ad cookies, third-party marketing pixels, or non-essential tracking cookies. Cloudflare Turnstile may load its challenge script where forms need bot protection.
