Sentry MCP server

The MCP Sentry server allows you to retrieve and analyze error reports, stack traces, and other debugging information directly from your Sentry.io account or self-hosted Sentry instance. This tool integrates Sentry issues into your AI assistant's context, making it easier to discuss and troubleshoot specific errors.

Installation Options

Using Smithery

Install the MCP Sentry server automatically via Smithery:

npx -y @smithery/cli install @javaDer/mcp-sentry-custom --client claude

Using uv (Recommended)

Run the server directly with uvx without installation:

uvx mcp-sentry-custom --auth-token YOUR_SENTRY_TOKEN --project-slug YOUR_PROJECT_SLUG --organization-slug YOUR_ORGANIZATION_SLUG --sentry-url YOUR_SENTRY_URL

Using pip

Install via pip:

pip install mcp-sentry-custom

Or with uv:

uv pip install -e .

Then run as a script:

python -m mcp_sentry

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "sentry" '{"command":"uvx","args":["mcp-sentry-custom","--auth-token","YOUR_SENTRY_TOKEN","--project-slug","YOUR_PROJECT_SLUG","--organization-slug","YOUR_ORGANIZATION_SLUG","--sentry-url","YOUR_SENTRY_URL"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "sentry": {
            "command": "uvx",
            "args": [
                "mcp-sentry-custom",
                "--auth-token",
                "YOUR_SENTRY_TOKEN",
                "--project-slug",
                "YOUR_PROJECT_SLUG",
                "--organization-slug",
                "YOUR_ORGANIZATION_SLUG",
                "--sentry-url",
                "YOUR_SENTRY_URL"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
