The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.

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
11/11 tools missing one or more hints — process_document (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_document (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); query_dust_agent (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +8 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.
Descriptions match behaviour
4 tools describe read intent but their handlers mutate — list_documents (line 14: fs.mkdir(UPLOADS_DIR, { recursive: true })); dust_agent_query (line 28: fs.appendFileSync(); dust_list_agents (line 28: fs.appendFileSync()
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
9/11 tool handlers declare input schemas (82%)
Declare an inputSchema with zod/joi/yup on every tool definition.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
7/11 tools referenced in tests (64%)
Write tests that reference each tool by name so every tool has at least one test.
Readable source code
1 file are minified or bundled, which is usually build output rather than concealment
Ship unminified, readable source.
Secrets not logged
1 secret value sent to error
Redact or omit secret values from log output.
Production dependencies are patched
0 critical, 4 high severity in production deps — @modelcontextprotocol/sdk@1.11.0 (high), @modelcontextprotocol/sdk@1.11.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dependency freshness
4/21 production deps abandoned (no release in 2+ years): @types/mongoose@2022-06-13 (4.2y), source-map-support@2023-06-09 (3.2y), node-fetch@2023-11-30 (2.8y)
Tool description accuracy
4 tools have description/behavior mismatches: list_documents: description implies read-only but handler writes/deletes/executes; dust_agent_query: description implies read-only but handler writes/deletes/executes; dust_list_agents: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
