MCP server

The same operations as the CLI, as tools for Claude Code, Cursor and Codex.

Install#

One command installs the skill and the MCP server entry for the agents it finds on the machine:

npx buildhound setup

Claude Code, Cursor and Codex are configured when present. The local server reuses the CLI's GitHub login.

Tools#

ToolWhat it does
scan_repoAudit a repository's workflows for wasted spend.
estimate_workflow_costMonthly cost of one workflow at a given number of runs.
explain_ruleWhat a rule such as R03 checks and how its fix works.
get_ratesThe rate tables, with source and verified date.
runner_statusMachines, heartbeats, running jobs and the failover map for an account.
runner_addConnect this machine. Needs confirm: true.
runner_setChange a machine's routing, policy or performance.
runner_removeDeregister a machine. Needs confirm: true.

Read-only by default#

Tools that read need nothing. Tools that change something take confirm: true and are marked destructive, so an agent asks first. When GitHub needs a person, a tool returns needs_human with one URL and a next step, the same contract as the CLI.
