Hosting

Remote, vendor-hosted; self-hosted endpoint can be used with a self-hosted Logfire instance

Transport

Streamable HTTP

Endpoint

https://logfire-us.pydantic.dev/mcp

Authentication

Browser OAuth on first connection. A Logfire API key as a bearer token is documented for headless/CI usage. Choose US or EU endpoint to match the Logfire data region.

Requirements

• Logfire account/project with access to desired telemetry
• Browser for interactive OAuth, or appropriately scoped Logfire API key for headless clients
• Organization policy may restrict external MCP access, read/write capabilities, and query budgets

Setup steps

1. Choose https://logfire-us.pydantic.dev/mcp for US-region data or https://logfire-eu.pydantic.dev/mcp for EU-region data.
2. Configure the remote Streamable HTTP endpoint in a supported client.
3. Authenticate in the browser when prompted; for Claude Code, official docs use claude mcp add --transport http logfire <endpoint> then claude mcp login logfire. For Codex, use codex mcp add logfire --url <endpoint>.
4. For Claude Code or Codex, the official Pydantic plugin can configure the MCP alongside Logfire skills.
5. Check accessible projects with a harmless query before inspecting traces. Respect organization read-only policy and avoid exposing sensitive telemetry in prompts.

The Pydantic guide documents 53 named tools across query, projects/auth, feedback, dashboards, variables, groups, alerts, channels, schedules, issue tracking and local development. agent-feedback is restricted by plan/policy; organization read-only policy and credential scope affect available calls.

  53

• Available tools depend on credentials and organization external-MCP policy.
• Logfire Cloud imposes concurrent-query limits and a daily organization query budget for MCP queries.
• Telemetry can contain user-controlled content; treat query results as untrusted data rather than instructions.
• The former pydantic/logfire-mcp local stdio repository is archived and no longer updated; the current supported service is remote.
• Some resource management tools write or delete data; organization admins can restrict external clients to read-only access.

• official tool reference

  The current official guide documents the full endpoint tool set by family; 53 named tools are captured here including agent-feedback (availability is plan/policy dependent). Credentials and organization policy scope the visible set.
