Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command packages/mcpcost/src/auth-cli.ts:36
    const child = spawn(cmd, args, { detached: true, stdio: 'ignore' });
Builds a database query by concatenation site/edge/rules.mjs:122, site/src/lib/db.ts:768
    console.log(`${existing ? `update (${existing.description ?? existing.ref ?? existing.id})` : 'add'} ${phase} ${rule.ref}\n  ${rule.expression}\n  ${rule.action}${rule.ratelimit ? ' ' + JSON.stringify(rule.ratelimit) : ''}`);

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

lookup
lookup_server
Latest probe of one server from the official MCP registry: status, protocol, tool count, exact token cost of its tool definitions in Claude, latency. Accepts the registry name (io.github.owner/name) or the server URL.
registry
registry_summary
Aggregates of the latest daily run: how many servers answer, token cost percentiles, protocol versions, heaviest servers.
server
check_server
Connects to an MCP server URL now (initialize and tools/list, no credentials, 10 s timeout) and reports status, protocol, tools and the token cost of the tool definitions: exact in Claude when the counter is available, else an estimate from the schema size. For registry servers prefer lookup_server.
servers
search_servers
Find servers by words in name, title, description or host, with optional filters, sorted by exact Claude token cost by default. Returns up to 20 servers per page; page numbers go to 20, after that pass the `next` cursor from the previous answer.

mcp-pulse — questions

Answers built from our own checks of this server.

What can mcp-pulse do?
It exposes 4 tools, read directly from the server on our last check. Among them: check_server, lookup_server, registry_summary, search_servers. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is mcp-pulse working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 469 ms. The bar chart above shows every period we have measured.
The registry lists mcp-pulse as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect mcp-pulse?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does mcp-pulse need an API key?
No. mcp-pulse completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
Is mcp-pulse open source?
The code is open source: it is published under the MIT licence, written in TypeScript, 2 stars on GitHub and 3 open issues. The licence covers the code in the repository, not the hosted service at mcp-pulse.ulehla.dev, which runs on its operator's own terms.
