memory-mcp (MateoGuerreroE/mcp-memory) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
Local-first MCP server for long-term memory of dev sessions. It indexes session metadata with embeddings in Postgres/pgvector, enables semantic search over past sessions, and resolves only relevant session files for context.
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.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
CLAUDE_CONFIG_DIR2. Writes the rendered files to $/commands/ if CLAUDE_CONFIG_DIR is set, otherwise ~/.claude/commands/ — the same resolution order the claude CLI itself uses (see mcp:register above).EMBEDDING_DIM384 Must match the embedding model's output dimension and the VECTOR(384) column in schema.sql — change both together.EMBEDDING_DTYPEq8 q8 = ~4x smaller weights, faster CPU inference, small accuracy tradeoff. Use fp32 for full precision.EMBEDDING_MODELXenova/bge-small-en-v1.5 Any @huggingface/transformers-compatible model.MODEL_CACHE_DIR.models/ Populated ahead of time by pnpm model:download; otherwise fetched lazily on first use.DATABASE_URLTool 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
3/3 tools missing one or more hints — index_session (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_sessions (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_session_files (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). 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 handlers catch errors
Only 0/3 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.16.0 (high), @modelcontextprotocol/sdk@1.16.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
