MCP Server

Connect your agent.

crv.sh exposes every eval tool as an MCP server. Point any MCP-compatible client at the remote endpoint and your agent can list models, run evals, validate outputs, and repair prompts.

Remote endpoint

The MCP server is available at:

https://crv.sh/api/mcp

Stateless HTTP transport. Every request is self-contained.

Available tools

list_modelsBrowse models with pricing and context windows

eval_promptRun a prompt against selected models

eval_batchRun against all models in one call

eval_suiteMulti-test-case pass/fail matrix

eval_rankRank models by composite score

eval_consistencyDetect flaky models with repeated runs

validate_outputCheck a response against JSON schema

suggest_system_promptAuto-repair a failing system prompt

Client config

Add this to your MCP client config. Works with Amp, Claude Code, Cursor, Windsurf, and any Streamable HTTP MCP client.
