A gateway for finding tools that use MCP, an open standard that lets AI agents connect to external tools and data. It searches available tools with text matching, relevance ranking, embeddings, or a combination of methods.

Use it to search an MCP tool collection by a name, description, or related meaning. It is intended for tool discovery through a gateway server.

It helps an agent locate a suitable tool when many tools are available, instead of loading or checking every tool individually. The input does not describe how search results are presented or used.

Security

Grade A, and why

mcp-gateway scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it installs

The manifest is a name and a version. 1 MCP server travel with it, and installing the plugin installs all of them. Each is measured on its own page, and each can be installed alone.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
