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. How we score → Why this is hard to score →
Endpoint Security74
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability65
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 496 tokens (~165/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability check failed: schema churn in the 14 days we've observed: 4 tool removals, 0 breaking changes, 0 auth/transport breaks, 3 additions. See how to fix → Fail
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (67% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_manual ~198
Get full manual text by name, e.g. manual_name="ls"; no package needed. manual_name is the command name (also matches aliases); package is an optional filter. Tries exact casing first, then a case-insensitive name/alias match. Search API selects latest indexed packages per scope, preferring Fedora when distribution is omitted, then newest Fedora RPM version across scopes. Explicit filters always apply; package_version can select historical manuals. Exact command names (sections 1/8) precede other names and aliases within the preferred distro. No locale fallback. Returns manual text with a distro/release and package/version header. Source-only manuals raise an error with extraction status.

No output schema declared.

get_targets ~55
List indexed distribution/release/repository/architecture scopes and counts. Use the returned values verbatim; targets such as CentOS 8, EPEL 9 or Fedora 43 are available only if they have been indexed.
Input schema present but exposes no named parameters.

No examples provided.
search ~168
Search manual text/metadata; return ranked hits, snippets and exact identities. Latest indexed package versions are used unless package_version is supplied. Omitted scope filters include all indexed distributions and releases. Supply query for relevance-ranked text search, or manual_name without query for name/alias lookup with Fedora-preferred recommendations and case-insensitive fallback. Pass next_cursor with identical arguments for the next live page; results can shift as indexing progresses. Filters are exact and case-sensitive.

How do I install the Manpage MCP server?
Manpage MCP is a hosted endpoint at https://manpage.ai/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.

What is the Manpage MCP server?
Manpage MCP is listed in the public MCP registry as ai.manpage/mcp. Search and read Linux manual pages with version-aware lookup and exact package provenance. This page covers its hosted endpoint (https://manpage.ai/mcp).
Is the Manpage MCP server safe to use?
Manpage MCP scores 67 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 Manpage MCP server expose?
Manpage MCP exposes 3 tools: get_targets, search, get_manual. Their descriptions and schemas cost roughly 421 tokens of context every time the server is loaded.
Does the Manpage MCP server require authentication?
No. We connected to Manpage MCP without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Manpage MCP server still maintained?
Manpage MCP is still listed as active in the MCP registry. We last reached this channel on 17 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
