Tomas Dvorak 485e41a817 feat(mcp): stdio MCP server exposing the full API as tools
Add containr-mcp so MCP-compatible agents (Claude, Cursor, Devin)
operate the platform directly — ROADMAP2 phase A3. Reuses the CLI's
thin client and PAT auth; zero duplicated resource logic.

- ~60 containr_* tools across projects, services, deployments, logs,
  exec, variables, databases, cron, templates, nodes, scaling, ha,
  security, gateway, admin, notifications, tokens
- declarative tool specs → {param} path substitution, GET extras become
  query params, remaining args form the request body
- destructive tools require confirm:true and return isError without it
- results are pretty JSON; API error envelopes surface as isError
- configured via CONTAINR_API_URL + CONTAINR_TOKEN env; official
  modelcontextprotocol/go-sdk over StdioTransport

Verified over stdio: initialize + tools/list, auth_status returns the
token owner's identity, projects list, destructive refusal, token
creation through MCP.
