The MCP server index that vets servers, not just lists them. Advisory screen before you install.
Available components
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 Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 6 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- 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 Usability80
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 509 tokens (~84/item across 6 items; 6 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
How do I install the mcpindex MCP server?
mcpindex is a hosted endpoint at https://mcpindex.ai/api/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.

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

No change was recorded against any check on this day. Stability & Change Management went from 93 to 97. That category is still filling its 30-day observation window: 28 days of observed history at the previous scan, 29 at this one. The score rises as the window fills, whether or not the server changes.

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 ~62
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 or recommend results). |
No output schema declared.
No examples provided.
recommend_mcp_for_task Recommend MCP servers for a task ~82
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". |
No output schema declared.
No examples provided.
search_mcp_servers Search MCP servers ~83
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). |
| limit | integer | – | Max results (default 10, max 50). |

What is the mcpindex MCP server?
mcpindex is an MCP server listed in the public MCP registry as io.github.gautamgb/mcp-server-mcpindex. The MCP server index that vets servers, not just lists them. Advisory screen before you install. This page covers its hosted endpoint (https://mcpindex.ai/api/mcp).
Is the mcpindex MCP server safe to use?
mcpindex scores 82 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 mcpindex MCP server expose?
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 509 tokens of context every time the server is loaded.
Does the mcpindex MCP server require authentication?
No. We connected to mcpindex without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the mcpindex MCP server still maintained?
mcpindex is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
