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 →
assess_server Assess server trust (advisory) ~77
Aggregated pre-flight trust assessment across all tools on an MCP server. Same verdict shape as check_tool_trust. Use for "is THIS server worth integrating?" decisions. v1 advisory; conformance monitored not enforced; verdicts may be UNVERIFIED if not yet probed.
| Name | Type | Req | Description |
|---|---|---|---|
| server_id | string | yes | Server slug to assess. |
No output schema declared.
No examples provided.
check_tool_trust Check tool trust (advisory) ~163
Pre-invocation advisory screen for a specific tool on an MCP server. Returns an advisory verdict object (directive ALLOW | DENY | REVIEW | UNVERIFIED, dimensions, freshness). At v1 the public screen produces REVIEW or UNVERIFIED only - ALLOW/DENY are reserved. Not the in-path gate (mcpindex-gate). Agents SHOULD treat UNVERIFIED as "human review required", never as ALLOW.
| Name | Type | Req | Description |
|---|---|---|---|
| server_id | string | yes | Registry slug from search_mcp_servers / recommend results, e.g. "io-github-microsoft-playwright-mcp" (NOT a short name like "github"). |
| tool_name | string | yes | Tool name as exposed by the server (e.g. "create_pull_request"). |
No output schema declared.
No examples provided.
compare_servers Compare MCP servers ~42
Side-by-side comparison of 2-5 MCP servers - quality scores, install paths, env vars.
| Name | Type | Req | Description |
|---|---|---|---|
| slugs | array | yes | Server slugs to compare. |
No output schema declared.
No examples provided.
get_install_command Get install command ~69
Get the exact install command for a given MCP server and client. Returns a JSON block ready to paste into the client config.
| Name | Type | Req | Description |
|---|---|---|---|
| client | string | yes | Target client. |
| server_slug | string | yes | Slug of the server (from search_mcp_servers or recommend_mcp_for_task results). |
No output schema declared.
No examples provided.
recommend_mcp_for_task Recommend MCP servers for a task ~92
Recommend the best MCP servers for a natural-language task. Returns top 3 ranked picks with reasoning, install commands, and quality scores. Use this when the user asks for the right MCP server for a task they want to do.
| Name | Type | Req | Description |
|---|---|---|---|
| task | string | yes | Natural-language description of the task, e.g. "read PDFs and write to S3" or "search GitHub and open a PR". |
No output schema declared.
No examples provided.
search_mcp_servers Search MCP servers ~85
Keyword + semantic search across every MCP server mcpindex indexes. Use when the user knows what tool category they want but not which server.
| Name | Type | Req | Description |
|---|---|---|---|
| category | string | – | Optional category filter (e.g. database, browser, github, productivity). |

mcpindex exposes 6 tools: recommend_mcp_for_task, search_mcp_servers, get_install_command, compare_servers, check_tool_trust, assess_server. Their descriptions and schemas cost roughly 528 tokens of context every time the server is loaded.

mcpindex is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
