Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

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
544/544 tools missing one or more hints — verify_receipt (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); listening_streaks (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); top_artists_by_range (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +541 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.
Destructive tools are labelled
3 tools perform destructive updates without destructiveHint — delete_playback_bookmark deletes at line 493 (unlink(file)); delete_playlist_snapshot deletes at line 603 (unlink(path)); prune_old_snapshots deletes at line 996 (unlink(d.path))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Descriptions match behaviour
16 tools describe read intent but their handlers mutate — resolve_artist (line 159: /^spotify:artist:(.+)$/.exec(args.query.trim())); backup_library (line 374: mkdir(dir, { recursive: true, mode: 0o700 })); episode_bookmark (line 196: mkdir(dirname(file), { recursive: true, mode: 0o700 }))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
427/544 tool handlers declare input schemas (78%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool test coverage
290/544 tools referenced in tests (53%)
Write tests that reference each tool by name so every tool has at least one test.
Tool description accuracy
15 tools have description/behavior mismatches: resolve_artist: description implies read-only but handler writes/deletes/executes; backup_library: description implies read-only but handler writes/deletes/executes; episode_bookmark: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
