How do I install the Klarefi MCP server?

Klarefi runs locally as an npm package, launched with npx -y @klarefi/mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 20 exposed · ~1,633 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 →

Common questions

What is the Klarefi MCP server?

Klarefi is an MCP server listed in the public MCP registry as com.klarefi/mcp. Complete regulated intake work and retrieve cited case files without deciding the case. This page covers its npm package (@klarefi/mcp).

Is the Klarefi MCP server safe to use?

Klarefi scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 22 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Klarefi MCP server expose?

Klarefi exposes 20 tools: create_connector_from_openapi, create_connector, delete_connector, create_intake_session, get_case, and 15 more. Their descriptions and schemas cost roughly 1,633 tokens of context every time the server is loaded.

Is the Klarefi MCP server still maintained?

Klarefi is still listed as active in the MCP registry. We last reached this channel on 22 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the Klarefi MCP server under?

Klarefi declares the ISC licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
