MCP tools · 10 exposed · ~932 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Opik MCP Server server expose?

Opik MCP Server exposes 10 tools: get-server-info, get-opik-help, get-opik-examples, get-opik-metrics-info, get-opik-tracing-info, and 5 more. Their descriptions and schemas cost roughly 932 tokens of context every time the server is loaded.

Is the Opik MCP Server server still maintained?

Opik MCP Server is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
