How to connect Runheed to Claude Code

One command adds the Runheed MCP server to Claude Code. After that, ask Claude what broke in production and it reads the errors itself.

Runheed is an error tracker with an MCP server: your app reports exceptions through a small SDK, and Claude Code reads them through the server below.

Steps

1. Create an agent key in Runheed under Settings > Agent keys (it starts with al_ and is shown once).
2. Run the command below in your project directory.
3. Start a new Claude Code session so it picks up the server.

Where the config lives: Claude Code stores MCP servers per project by default; add --scope user to make Runheed available in every project.

claude mcp add runheed -e RUNHEED_API_KEY=al_your_key -- npx -y https://runheed.com/dl/runheed-mcp-0.1.0.tgz

# every project:
claude mcp add --scope user runheed -e RUNHEED_API_KEY=al_your_key -- npx -y https://runheed.com/dl/runheed-mcp-0.1.0.tgz

# check it is connected
claude mcp list

The npm and PyPI releases are not out yet, so these commands install the same package files straight from runheed.com. Nothing else changes when the registry versions ship.

The server runs with npx, so Node.js 18 or newer must be installed on the machine.

Check that it works

Ask: "Use runheed_get_recent and tell me what failed in production today."

If the agent reports a problem

Every Runheed tool error says what went wrong and where to fix it. The common ones:

"RUNHEED_API_KEY is not set"

The key is missing from the server env. Add it and restart the client.

"That is a project key (pk_...)"

You pasted the DSN key. The MCP server needs an agent key that starts with al_.

"This agent key is not recognised"

Typo, or the key was revoked. Create a new one in Settings; keys are shown once.

"The workspace has no active plan"

Choose a plan or fix the card in Settings > Billing. The key works again as soon as the plan is active.

"No errors have been reported yet"

The agent side works. Check that the app has RUNHEED_DSN set and calls runheed.init() at startup.

Still need the SDK side? See the setup docs, or tell Claude Code: Read https://runheed.com/SETUP.txt and set up error tracking. Official reference: Claude Code MCP docs.
