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.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
aim_memory_storeStore new memories. Use this to remember people, projects, concepts, or any information worth persisting. AIM (AI Memory) provides persistent memory for AI assistants. The 'aim_memory_' prefix groups all memory tools together. WHAT'S STORED: Memories have a name, type (person/project/concept/etc.)…
aim_memory_linkLink two memories together with a relationship. Use this to connect related information. RELATION STRUCTURE: Each link has 'from' (subject), 'relationType' (verb), and 'to' (object). - Use active voice verbs: "manages", "works_at", "knows", "attended", "created" - Read as: "from relationType to" (e…
aim_memory_add_factsAdd new facts to an existing memory. Use this to append information to something already stored. IMPORTANT: Memory must already exist - use aim_memory_store first. Throws error if not found. RETURNS: Array of {entityName, addedObservations} showing what was added (duplicates are ignored). DATABAS…
aim_memory_forgetForget memories. Removes memories and their associated links. DATABASE SELECTION: Entities are deleted from the specified database's knowledge graph. LOCATION OVERRIDE: Use the 'location' parameter to force deletion from 'project' (.aim directory) or 'global' (configured directory). Leave blank fo…
aim_memory_remove_factsRemove specific facts from a memory. Keeps the memory but removes selected observations. DATABASE SELECTION: Observations are deleted from entities within the specified database's knowledge graph. LOCATION OVERRIDE: Use the 'location' parameter to force deletion from 'project' (.aim directory) or …
aim_memory_unlinkRemove links between memories. Keeps the memories but removes their connections. DATABASE SELECTION: Relations are deleted from the specified database's knowledge graph. LOCATION OVERRIDE: Use the 'location' parameter to force deletion from 'project' (.aim directory) or 'global' (configured direct…
aim_memory_read_allRead all memories in a database. Returns every stored memory and their links. FORMAT OPTIONS: - "json" (default): Structured JSON for programmatic use - "pretty": Human-readable text format DATABASE: Reads from the specified 'context' database, or master database if not specified. EXAMPLES: - aim…
aim_memory_searchSearch memories by keyword. Use this when you don't know the exact name of what you're looking for. WHAT IT SEARCHES: Matches query (case-insensitive) against: - Memory names (e.g., "John" matches "John_Smith") - Memory types (e.g., "person" matches all person memories) - Facts/observations (e.g., …
aim_memory_getRetrieve specific memories by exact name. Use this when you know exactly what you're looking for. VS aim_memory_search: Use aim_memory_get for exact name lookup. Use aim_memory_search for fuzzy matching or when you don't know exact names. RETURNS: Requested entities and relations between them. Non…
aim_memory_list_storesList all available memory databases and show current storage location. DATABASE TYPES: - "default": The master database (memory.jsonl) - used when no context is specified - Named databases: Created via context parameter (e.g., "work" -> memory-work.jsonl) RETURNS: {project_databases: [...], global…
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

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
10/10 tools missing one or more hints — aim_memory_store (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); aim_memory_link (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); aim_memory_add_facts (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +7 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 test coverage
Only 0/10 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 1 high severity in production deps — @modelcontextprotocol/sdk@1.0.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

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.
