analytics for MCP servers

Know who's actually using your MCP server.

Which clients connect. Which tools get called. Where agents hit errors. One dashboard, one line of code — and never a byte of your users' payloads.

install

One line. Under sixty seconds.

track() wraps your FastMCP server and instruments every tool automatically. No decorators, no config file. Fire-and-forget: if Pulse is unreachable, events drop silently and your server never notices.

server.pypip install mcpulse
from mcpulse import track

mcp = track(mcp, key="pk_live_...")

what you see

The three questions every MCP author is guessing at today.

Which clients connect?

The MCP handshake already announces every client. Pulse surfaces it: Claude, Cursor, Windsurf, custom agents — by name and version, over time.

claude-ai46%
cursor24%
windsurf12%

Which tools earn their keep?

Calls, error rate, and p95 latency per tool. Find the tool nobody uses — and the one that times out for every agent that touches it.

PAYLOAD: NOT COLLECTED

never leaves your server

  • ✕ tool arguments
  • ✕ tool results
  • ✕ prompts
  • ✕ error messages
  • ✕ IP addresses

the only fields that exist

  • ✓ tool name
  • ✓ client name + version
  • ✓ duration
  • ✓ status + error class
  • ✓ salted session hash

This isn't a setting — it's the schema. The ingest API has no field for payloads, so nothing you didn't see here can be stored, leaked, or subpoenaed. Session hashes are salted on your machine with a salt we never receive.

Every server gets a live badge and an optional public stats page. Adoption numbers are the best marketing an open-source MCP server has — now you can prove yours.
