Whose server it is
  • Registry namecn.infimeta/public-source-searchverified in the MCP registry

The registry name sits under infimeta.cn. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-29 the server answered initialize and tools/list without a sign-in. First answer in 514 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: search Wikipedia, Crossref, Hacker News and Stack Overflow; answer questions with traceable public sources; query public knowledge through an API or MCP.
  • Checked on 5 of the 7 days it takes to judge reliability.

Once connected

  • For "search Wikipedia, Crossref, Hacker News and Stack Overflow", the likely first call is search_public_sources.
  • For "answer questions with traceable public sources", the likely first call is search_public_sources.
  • For "query public knowledge through an API or MCP", the likely first call is search_public_sources.
  • Parameters are untyped or undescribed in 2 of 2 tools: check arguments before calling.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

Tools it offers2 tools · read 2026-10-29
  • search_public_sources

    Search encyclopedias, scholarly metadata and communities. Not whole-web search. Optional purpose does not affect results. Submitted queries are recorded for research.

  • report_search_gap

    Optionally report whether a previous search helped and which information is missing. Stored privately for research.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "public-source-search": {
      "type": "http",
      "url": "https://infimeta.cn/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http infimeta https://infimeta.cn/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://infimeta.cn/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
