personal-brain-mcp
A personal-life database with 47 tools across 13 domains, enabling semantic search and retrieval of memories, food, home, health, and more from any MCP-aware AI client.
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.

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.

Tool annotations
1/54 tools have annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
54/54 tools missing one or more hints — add_recipe (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); anniversaries (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ask_brain (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +51 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
28 tools perform destructive updates without destructiveHint — anniversaries overwrites at line 53 (ctx.supabase.from("anniversaries").update({ active: false })); bucket_list overwrites at line 59 (ctx.supabase.from("bucket_list").update(updates)); content_queue overwrites at line 58 (ctx.supabase)
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
4 tools describe read intent but their handlers mutate — log_household_expense (line 36: ctx.supabase); packing_list (line 43: ctx.supabase); tax_documents (line 51: ctx.supabase.from("tax_documents").insert(doc))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
53/54 tool handlers declare input schemas (98%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool test coverage
Only 2/54 tools referenced in tests (4%)
Write tests that reference each tool by name so every tool has at least one test.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Tool description accuracy
4 tools have description/behavior mismatches: log_household_expense: description implies read-only but handler writes/deletes/executes; packing_list: description implies read-only but handler writes/deletes/executes; tax_documents: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
