## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-23.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 60/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 547 tokens (~273/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## Install

### How do I install the Agent Docs MCP server?

Agent Docs is a hosted endpoint at https://agent-docs-mcp.onrender.com/mcp/, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (2)

### `search_docs` (~295 tokens)

Search official agent docs

Search the official documentation of Claude Code, Cursor, OpenAI Codex and MCP. Use it before answering any question about using, configuring or administering these products. Not for other products or general programming. If the answer could differ between products and the user hasn't said which one, ask.

Returns one passage per page, with the page's one-line description and a
relevance score; under ~0.5 means the docs probably don't cover it. One
topic per call: split multi-part questions. Need more than the passage?
Call read_section(url), or read_section(url, heading) for one of the
passage's other_sections.

Input parameters:

- `limit` (integer): Pages to return, 1-20 (default 8).
- `product`: Only this product. Set it when the user has named the product, now or earlier in the conversation. Otherwise leave it empty: an unfiltered search still finds product-specific pages, while a wrong pro…
- `query` (string, required): What to find, in English: keywords or a short question, e.g. "<product> <feature> <what you need>".
- `response_format` (string): `concise` (default): first 300 characters of each passage, enough to choose. `detailed`: full passages, about 800 tokens each. Start concise; re-run detailed with a small limit for the pages you need.

Output parameters:

- `index_snapshot`: Date the documentation was indexed (ISO); null if unknown.
- `passages` (array): Ranked documentation passages. Empty if nothing matched.

### `read_section` (~205 tokens)

Read a section of an agent doc page

Read a page found by search_docs.

Without a heading: the page's description and outline (top-level sections
with subsection counts). With a heading: that section's full text,
including its subsections; continue long sections with next_offset.
outline_depth=3 also lists subsections; use it only on long pages to find
one specific subsection.

Input parameters:

- `heading`: Heading to read, as listed in the outline (leading #s optional). Exact text first, case-insensitive, then a unique partial match; use 'Parent > Heading' when two headings share a name. Leave unset to…
- `offset` (integer): Character offset into the section; pass the previous next_offset to continue a long section.
- `outline_depth` (integer): Outline depth when no heading is given: 2 lists top-level sections with subsection counts, 3 also lists the subsections.
- `url` (string, required): Page URL exactly as search_docs returned it.

Output parameters:

- `description` (string): One sentence on what the page is.
- `heading`: Path of the section returned, e.g. 'Hooks > PreToolUse'; null when only the outline was asked for.
- `next_offset`: Pass as offset to read the rest; null when nothing is left.
- `offset` (integer): Offset of `text` within the section.
- `outline` (array): Top-level sections as '## Text (N subsections)' when no heading was asked for (at most 40 lines, then '+N more sections'); empty otherwise.
- `text` (string): Section markdown from its heading to the next heading of the same or higher level, at most 8,000 characters per call.
- `title` (string): Page title.
- `total_chars` (integer): Length of the whole section.
- `url` (string): Page URL.

## Common questions

### What is the Agent Docs MCP server?

Agent Docs is an MCP server listed in the public MCP registry as io.github.KonstantinStarovoytov/agent-docs. Search the official docs of Claude Code, Cursor, OpenAI Codex and MCP, refreshed daily. This page covers its hosted endpoint (https://agent-docs-mcp.onrender.com/mcp/).

### Is the Agent Docs MCP server safe to use?

Agent Docs scores 75 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Agent Docs MCP server expose?

Agent Docs exposes 2 tools: search_docs, read_section. Their descriptions and schemas cost roughly 500 tokens of context every time the server is loaded.

### Does the Agent Docs MCP server require authentication?

Yes. Agent Docs asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

### Is the Agent Docs MCP server still maintained?

Agent Docs is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
