Exposed MCP Tools (4)

safe

find_exceptions_in_file

Retrieves details about the most recent exceptions in a specified file.

Read-only operation that retrieves exception data.

moderate

arbitrary_query

Executes an arbitrary SQL query on the Pydantic Logfire database.

Allows arbitrary queries, which could expose sensitive data if not carefully constructed.

safe

logfire_link

Creates a link to view a specific trace in the Logfire UI.

Generates a URL, posing minimal risk.

safe

schema_reference

Provides the database schema for the Logfire DataFusion database.

Read-only access to schema information.

Safety Assessment

The Logfire MCP server is relatively safe for read-only telemetry data retrieval. Risks are primarily associated with the exposure of the read token and the potential for information leakage through poorly constructed queries. Using the remote MCP server is recommended for enhanced security.

Read-only access to telemetry data via API.
Authentication via read token.
No direct execution of arbitrary code on the server.
Remote MCP server option available, managed by Pydantic Logfire.

Exposure of telemetry data if read token is compromised.
Potential for information leakage via arbitrary queries if not carefully constructed.
Dependency on Pydantic Logfire's infrastructure and security.
Deprecated local server option increases attack surface if used.
