## Summaries

### 13. MongoDB MCP Server, A (78.6)

MongoDB's official MCP server for querying and managing databases and Atlas resources, with configurable tool access. `--readOnly` drops every create, update and delete tool, and `--disabledTools` trims by name, category or operation type. 53 tools with Atlas credentials, and most database tool descriptions are one line.

- Capabilities: db.document, db.admin

### 30. Supabase API + MCP, BB (75.8)

Hosted Postgres with an auto-generated REST API (PostgREST), GraphQL, auth, storage, realtime and Edge Functions, plus a Management API and an official MCP server. OAuth 2.1 with dynamic client registration, plus personal access tokens scoped to chosen projects and permissions. Several multi-hour platform incidents between 27 August and 30 September.

CoinMarketCap market-data endpoints for cryptocurrency and DEX quotes, with per-call USDC payments through x402. x402 on four endpoints at $0.01 a call, with payment taken only when data is returned. Only four endpoints are sold by x402, and none of them covers history.

### 266. Filesystem (MCP reference server), C (59.4)

Reference server for secure local file operations (read, write, edit, search, directory listing) restricted to allowed directories supplied as arguments or via MCP Roots. All 14 tools carry `readOnlyHint`, and the four write tools set `destructiveHint` and `idempotentHint` accurately. No depth limit on `directory_tree` and no size cap on reads or search results.

- Capabilities: fs.local

### 322. Memory (MCP reference server), C (54.4)

Knowledge-graph persistent memory reference server (entities, relations, observations) stored as JSONL at MEMORY_FILE_PATH. Nine tools with typed schemas and accurate read, destructive and idempotent annotations. No pagination or limits. `read_graph` returns everything and `search_nodes` every match.

- Capabilities: db.sql, db.admin

### 449. PostgreSQL (archived MCP reference server), F (18.6)

Archived PostgreSQL reference MCP server for SQL queries. Its read-only transaction wrapper has a documented bypass. The server exposes one small query tool. Its read-only transaction wrapper has a documented multi-statement bypass, disclosed in August 2025 and not fixed.
