**Summary:** 88 tools total — 32 available in Dev mode, 56 Full-only.

Notes:
- Dev mode focuses on developer workflows (builds, tests, logs) and excludes infrastructure/admin tools to reduce context size (~12k tokens saved).
- Admin tools (agents, VCS roots, users, compatibility checks) require Full mode.
- **New in v2.1.0:** Runtime mode switching via `get_mcp_mode` and `set_mcp_mode` tools.
- **New in v2.1.1:** Full CRUD for project and output parameters.
