MCP server for agent frameworks
Bolvrk as a first-class tool inside Claude, Cursor, and agent frameworks: agents call the verifier directly and read structured findings. Self-hosted on every plan; hosted with the full corpus on Team and above.
A Model Context Protocol server that exposes the verifier as tools, so an agent inside Claude, Cursor or any MCP-aware framework calls it directly and reads the structured findings without shelling out. Every tool result carries the findings JSON contract — the same object bolvrk check --json prints — plus a text summary the model reads.
Two servers, one contract. npx bolvrk mcp runs on the machine the agent runs on, over stdio, with the rules the public CLI bundles: check (Postgres, SQLite alpha, optional live schema from a database URL), secrets (text or files, always local) and explain. Every plan, Free included, nothing leaves the machine.
The hosted server at bolvrk.com/api/mcp authenticates with a team token and adds what the hosted service has: the full corpus, live schema through stored connections, the team policy, and the run log — every check an agent makes lands there with source "mcp". Its tools are check, policy, rules and rule. There is no secrets tool hosted, because a credential scan never leaves the machine. Team plan and above.
# self-hosted, every plan
claude mcp add bolvrk -- npx -y bolvrk mcp
# hosted, Team and above
claude mcp add --transport http bolvrk https://bolvrk.com/api/mcp --header "Authorization: Bearer blv_..."Skills
The public repository ships a skills library next to the server: short SKILL.md files that tell an agent when to reach for the verifier — check a migration before committing it, scan a diff or a log for secrets before pasting it anywhere, explain a backfill against a shadow database. Copy one into your agent's skills folder and the workflow comes with it.
The CLI is open source and needs no account: npx bolvrk check migration.sql
