Pydantic Logfire MCP Server

1# Pydantic Logfire MCP Server
2 
3This repository contains a Model Context Protocol (MCP) server with tools that can access the OpenTelemetry traces and
4metrics you've sent to Pydantic Logfire.
5 
6## Remote MCP Server (Recommended)
7 
8Pydantic Logfire provides a hosted remote MCP server that you can use instead of running this package locally.
9This is the easiest way to get started with the Logfire MCP server.
10 
11To use the remote MCP server, add the following configuration to your MCP client.
12 
13**Choose the endpoint that matches your Logfire data region:**
14 
15- **US region** — `logfire-us.pydantic.dev`
16- **EU region** — `logfire-eu.pydantic.dev`
17 
18For **US region** (`logfire-us.pydantic.dev`):
19```json
20{
21  "mcpServers": {
22    "logfire": {
23      "type": "http",
24      "url": "https://logfire-us.pydantic.dev/mcp"
25    }
26  }
27}
28```
29 
30For **EU region** (`logfire-eu.pydantic.dev`):
31```json
32{
33  "mcpServers": {
34    "logfire": {
35      "type": "http",
36      "url": "https://logfire-eu.pydantic.dev/mcp"
37    }
38  }
39}
40```
41 
42> [!NOTE]
43> The remote MCP server handles authentication automatically through your browser. When you first connect,
44> you'll be prompted to authenticate with your Pydantic Logfire account.
45 
46> [!NOTE]
47> If you want to run logfire-mcp locally, check the [OLD_README.md](OLD_README.md) file.

49## Configuration with well-known MCP clients
50 
51The examples below use the **US region** endpoint. Replace the URL with `https://logfire-eu.pydantic.dev/mcp` if you are using the EU region.
52 
53### Configure for Cursor
54 
55Create a `.cursor/mcp.json` file in your project root:
56 
57```json
58{
59  "mcpServers": {
60    "logfire": {
61      "type": "http",
62      "url": "https://logfire-us.pydantic.dev/mcp"
63    }
64  }
65}
66```
67 
68### Configure for Claude Code
69 
70Run the following command:
71 
72```bash
73claude mcp add logfire --transport http https://logfire-us.pydantic.dev/mcp
74```
75 
76### Configure for Claude Desktop
77 
78Add to your Claude settings:
79 
80```json
81{
82  "mcpServers": {
83    "logfire": {
84      "type": "http",
85      "url": "https://logfire-us.pydantic.dev/mcp"
86    }
87  }
88}
89```
90 
91### Configure for Cline
92 
93Add to your Cline settings in `cline_mcp_settings.json`:
94 
95```json
96{
97  "mcpServers": {
98    "logfire": {
99      "type": "http",
100      "url": "https://logfire-us.pydantic.dev/mcp"
101    }
102  }
103}
104```
105 
106### Configure for VS Code
107 
108Make sure you [enabled MCP support in VS Code](https://code.visualstudio.com/docs/copilot/chat/mcp-servers#_enable-mcp-support-in-vs-code).
109 
110Create a `.vscode/mcp.json` file in your project's root directory:
111 
112```json
113{
114  "servers": {
115    "logfire": {
116      "type": "http",
117      "url": "https://logfire-us.pydantic.dev/mcp"
118    }
119  }
120}
121```
122 
123### Configure for Zed
124

126 
127```json
128{
129  "context_servers": {
130    "logfire": {
131      "type": "http",
