Analysis summary

MongoDB MCP Server is an officially published MCP server from MongoDB. Anomity scores its risk at 45 out of 100 (medium). It matches 1 dangerous capability combination.

MongoDB's official server gives agents access to clusters, collections, and documents — running queries and aggregations, inspecting schemas, and managing Atlas resources.

Capabilities are database read and write, outbound network access, and credential access, which includes the database-exfiltration combination. Document databases raise a specific version of the problem: with no fixed schema, an agent exploring collections discovers whatever is stored there, and application databases accumulate fields nobody documented. Use a read-only user scoped to specific collections for assistant work, and keep write access for deliberate, reviewed operations.

Why this entry scored 45 out of 100

This profile starts at the catalog's neutral base of 50. Because the entry is officially published, trust adjusts the score by -40. Declared high-risk capabilities add +20 (capped at +30). It matches 1 dangerous capability combination, which contributes additional severity weight. The clamped result is 45, placing it in the medium band.

Capabilities

Every capability the entry declares, with the security implication of each.

  • database:read Database read
    Reads from connected databases. Useful for query and analytics agents; risky when combined with outbound network.
  • database:write Database write
    Writes to connected databases. High-impact; combined with outbound network is treated as exfiltration-class.
  • network:outbound Outbound network
    Can make outbound network requests. Required for hosted model providers and remote APIs; also the path for data exfiltration if combined with read access.
  • credentials:access Credentials access
    Reads provider API keys, OAuth tokens, or other secrets from the host keychain or environment.
