Self-hosted, provider-neutral agent runtime for teams: governed tools and permissions, Slack/Telegram/Teams channels, scheduled jobs, memory, Node SDK and APIs, audit-first on Postgres.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
76/76 tools missing one or more hints — mcp_list_tools (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); mcp_search_tools (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); mcp_describe_tool (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +73 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
52/75 tool handlers declare input schemas (69%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 1/75 tool handlers wrap calls in try/catch (1%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
Only 4/76 tools referenced in tests (5%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
12 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Domain consistency
npm scope @gantry doesn't match GitHub owner knacklabs
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
