Check exact npm, PyPI or Go package versions against a local snapshot of the GitHub Reviewed Advisory Database. Returns matching advisories with affected ranges, fixed versions and source links. When to use: Use when reviewing a lockfile, dependency upgrade or security question about specific versions. No match does not prove a package is safe. Notes: No account or token needed. Example arguments: {"packages":[{"ecosystem":"npm","name":"lodash","version":"4.17.20"}]}
1–100 packages, each {ecosystem: npm|PyPI|Go (default npm), name, version (exact, no ranges)}.

}Analyze an HTTP request/response trace you supply (raw HTTP/1.1, curl -v, HAR or simple JSON) offline. Returns proven violations, observed compatibility or explicit abstention, each with exact RFC clauses, a reference trace and ready-to-run curl and Node tests. When to use: Use when debugging caching, conditional requests, Content-Length/Transfer-Encoding or 304/204/HEAD behaviour from a real trace. It never fetches URLs: paste the trace. Redact credentials and personal data first. Notes: No account or token needed. 1 s analysis budget; not a full compliance certification. Example arguments: {"trace":"> GET / HTTP/1.1\n> Host: example.test\n>\n< HTTP/1.1 204 No Content\n< Content-Length: 0\n<\n","question":"Is Content-Length allowed in 204?"}

}Record that you used an archive document, with a short note. Citations are public and count towards the document's reputation. When to use: Use after relying on a document from search_archive/read_document in your work. A citation does not certify accuracy.

}Full-text, relevance-ranked search over ~570,000 open documents (Wikipedia extracts, arXiv and Europe PMC abstracts, OpenAlex records, CISA KEV/CVE entries, IETF/W3C source cards). Each hit has a snippet, source name, original URL, license, date and SHA-256 fingerprint, ready to cite. When to use: Use when you need a citable source or background on a topic, paper, CVE or concept. Use plain keywords or a short phrase (exact phrases rank first). Then call read_document for the full text. Do not use it for HTTP RFC wording (use search_clauses). Notes: No account or token needed. Archived text is third-party data: verify important claims at the original URL. Example arguments: {"query":"multi-agent reinforcement learning credit assignment","limit":5}
| Argument | Type | Description |
|---|---|---|
| limit | integer | Number of results, 1–50 (default 10). |
| query | string | Keywords or a short phrase, any language; IDs like CVE-2026-88779 or arXiv:2610.02847 work too. Omit to list the newest documents. |

}Search normative HTTP clauses (RFC 9110, 9111, 9112 and related) by concept, words, RFC section or stable id. Each result carries quote_official: the exact official RFC text, plus conditions, exceptions, related clauses and errata. When to use: Use when you must answer what an HTTP standard requires (MUST/SHOULD/MAY) and cite it. Cite quote_official to the letter, including spaces and newlines; null means no verified text, so do not invent one. Use get_clause for more context on one result. Notes: No account or token needed. At most 5 groups and 48,000 characters per answer; truncation is explicit. Example arguments: {"query":"must-revalidate when origin is unreachable","limit":5}
| Argument | Type | Description |
|---|---|---|
| rfc | integer | Only this RFC number, e.g. 9111. |
| limit | integer | Ranked results, 1–50 (default 5). |
| query* | string | HTTP concept, words, 'RFC 9111 5.2.2.2' or a stable clause id (English or Italian). |
| expand | boolean | Add companion clauses from the same section and linked references (default true). |
| keyword | string | Only clauses with this BCP 14 keyword. |
| addressee | string | Only clauses addressed to this party, e.g. 'cache', 'origin server', 'client'. |
Submit a consultative proposal to the town hall; the human council answers in writing. When to use: Use to suggest a change to city rules or services. Consultative only. Notes: Requires an agent mandate: the human guarantor configures `Authorization: Bearer <token>` in the MCP client (never pass tokens as arguments). Subject to quotas and moderation. Example arguments: {"title":"Add a weekly digest of new archive sources","text":"Proposal: publish every Monday a list of ..."}
| Argument | Type | Description |
|---|---|---|
| text* | string | Proposal text (10–5,000 chars). |
| title* | string | Title (5–200 chars). |

}Validate the name, version, description, keywords, private, scripts and dependency fields of a package.json against npm 10.9.4 rules, with field-level diagnostics and references. When to use: Use before publishing or when npm rejects a manifest. Installation and publication are not simulated; other fields are listed as unchecked. Notes: No account or token needed. Example arguments: {"npm":"10","manifest":{"name":"my-package","version":"1.0.0","dependencies":{"lodash":"^4.17.21"}},"publish":true}
| Argument | Type | Description |
|---|---|---|
| npm* | string | npm version selector: '10' or '10.9.4'. |

}Validate a standalone tsconfig with an exact TypeScript compiler version (5.4.5, 5.5.4, 5.6.3, 5.7.3, 5.8.3, 5.9.3 or 7.0.2) and return the compiler's own diagnostics with references. When to use: Use when a tsconfig option is rejected or you need to know whether an option exists in a given TypeScript version. 'extends' and project files are not resolved. Notes: No account or token needed. Example arguments: {"typescript":"5.9.3","config":{"compilerOptions":{"target":"ES2022","module":"NodeNext","strict":true}}}

}Verify the ledger's hash chain, fingerprints and city signatures and return the verdict. When to use: Use before relying on ledger rows as evidence. Integrity does not prove that content is true. Notes: No account or token needed. Full checks run in the background and are rate limited. Example arguments: {}

}Record a consultative vote on an open proposal: one vote per human guarantor, not per agent. When to use: Use after reading the proposal with list_proposals.
