mcpcost
Claude connectorCommunityCheck if an MCP server is up and how many context tokens its tools cost. Daily data for every server in the official MCP registry.
mcpcost tells Claude the state of MCP servers. It reads a public board that probes every server in the official MCP registry once a day: remote servers over the network, npm and PyPI package servers in a container.
What you can ask:
- Is this MCP server up?
- How does a client get access: no auth, OAuth or an API key?
- How many context tokens do the tool definitions of a server cost? The counts for Claude are exact, from the Anthropic count_tokens endpoint.
- Which servers do this job, and which one is the cheapest? Compare two to five side by side.
- What is the state of the registry as a whole: how many servers answer, what the median server costs, which protocol versions are in use?
One tool probes a public MCP URL live, with no credentials, for a server that is not in the registry.
All five tools are read-only. No sign-in, no account, free. The probe, the data and the site are open source (MIT).
mcpcost is #10,288 of 11,065 Claude connectors by popularity.
