Bugfender MCP server

@bugfender/mcp

Bugfender MCP server for local stdio clients such as Cursor, Claude Code, Codex, and Gemini CLI.

What It Provides

• user-scoped Bugfender read access through MCP
• automatic access-token refresh when a refresh token is configured
• logs, devices, app metadata, crash aggregation, and issue aggregation tools
• SDK snippet retrieval for app onboarding
• resource templates for snippets, logs, and issue groups
• companion Bugfender skills distributed from bugfender/bugfender-skills

Maintainers

• development workflow: DEVELOPMENT.md
• release and publish flow: RELEASING.md

Install

npx -y @bugfender/mcp

After adding or updating the MCP server in your IDE or agent, restart that client so it reloads the new MCP configuration cleanly.

If you are running from inside this repository checkout, do not use npx @bugfender/mcp or npx -p @bugfender/mcp bugfender-mcp. npm can resolve the current package instead of the published tarball and fail with bugfender-mcp: not found.

For local development, build and run the generated entrypoint directly:

pnpm build
pnpm start

Configuration

• BUGFENDERAPITOKEN: required access token
• BUGFENDERREFRESHTOKEN: recommended for automatic token refresh
• BUGFENDERAPIURL: optional override, defaults to https://dashboard.bugfender.com/api
• ~/.bugfender/mcp.json: optional config file and local token store for rotated credentials

{
  "default": {
    "apiToken": "YOUR_ACCESS_TOKEN",
    "refreshToken": "YOUR_REFRESH_TOKEN",
    "apiUrl": "https://dashboard.bugfender.com/api"
  }
}

When a refresh token is provided, the MCP stores rotated credentials in ~/.bugfender/mcp.json so automatic refresh survives restarts. Updating the IDE config with a newly generated refresh token resets that local state.

If you are using local or self-hosted Bugfender credentials, BUGFENDERAPIURL must point to the matching backend. For example, local credentials generated from https://dashboard:3000 will not work against https://dashboard.bugfender.com/api.

Cursor / Claude Code

{
  "mcpServers": {
    "bugfender": {
      "command": "npx",
      "args": ["-y", "@bugfender/mcp"],
      "env": {
        "BUGFENDER_API_TOKEN": "YOUR_ACCESS_TOKEN",
        "BUGFENDER_REFRESH_TOKEN": "YOUR_REFRESH_TOKEN",
        "BUGFENDER_API_URL": "https://dashboard.bugfender.com/api"
      }
    }
  }
}

Codex CLI

codex mcp add bugfender \
  --env BUGFENDER_API_TOKEN='YOUR_ACCESS_TOKEN' \
  --env BUGFENDER_REFRESH_TOKEN='YOUR_REFRESH_TOKEN' \
  --env BUGFENDER_API_URL='https://dashboard.bugfender.com/api' \
  -- npx -y @bugfender/mcp

After running codex mcp add, restart the Codex session before testing whoami or list_apps.

Gemini CLI

gemini mcp add bugfender npx -y @bugfender/mcp \
  --env BUGFENDER_API_TOKEN='YOUR_ACCESS_TOKEN' \
  --env BUGFENDER_REFRESH_TOKEN='YOUR_REFRESH_TOKEN' \
  --env BUGFENDER_API_URL='https://dashboard.bugfender.com/api'

After running gemini mcp add, start a new Gemini CLI session or reload MCP servers before testing whoami or list_apps.

Codex App

In the custom MCP server form:

• Name: bugfender
• Command to launch: npx
• Argument 1: -y
• Argument 2: @bugfender/mcp
• BUGFENDERAPITOKEN: YOURACCESSTOKEN
