mcp-pulse
Health and token cost of every remote MCP registry server, probed daily. Look up, search, or probe.
Should I use this
Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tool inventory
Tools (4)
⚪lookup_server(nameOrUrl)
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.

"properties": {
"nameOrUrl": {

"required": [

"additionalProperties": false,
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢search_servers(query, status, sort, page)
Find servers by words in name, title, description or host, with optional filters, sorted by token cost by default. Returns up to 20 servers per page.

}🟢check_server(url)
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.

}⚪registry_summary
Aggregates of the latest daily run: how many servers answer, token cost percentiles, protocol versions, heaviest servers.
