# Claude Code

Connect Dstl8 to Claude Code for terminal-based observability access.

### Prerequisites

* Node.js 18+
* Claude Code installed
* Your [MCP endpoint and API token](/controltheory-documentation/dstl8-docs/mcp-integration.md)

### Setup

Run the following in your terminal (not inside Claude Code):

```bash
claude mcp add-json Dstl8 '{
  "command": "npx",
  "args": [
    "-y",
    "mcp-remote",
    "https://<org_id>.app.dstl8.ai/mcp",
    "--header",
    "Authorization: Bearer <your-token>"
  ]
}'
```

Replace `<org-id>` and `<your-token>` with your credentials from **Settings → Integrations → MCP**.

### Scoping

The command above saves to your local project config (`.mcp.json`). To make Dstl8 available across all your projects:

```bash
claude mcp add-json Dstl8 --scope user '{
  "command": "npx",
  "args": [
    "-y",
    "mcp-remote",
    "https://<org_id>.app.dstl8.ai/mcp",
    "--header",
    "Authorization: Bearer <your-token>"
  ]
}'
```

### Verify

Inside Claude Code, run:

```
/mcp
```

You should see `Dstl8` with status **connected**.

### Updating

To update your endpoint or token, re-run the setup command with `--overwrite`:

```bash
claude mcp add-json Dstl8 '{
  ...
}' --overwrite
```

### Troubleshooting

**Server shows "failed"** — Run `mcp-remote` directly to see the underlying error:

```bash
npx -y mcp-remote https://<org_id>.app.dstl8.ai/mcp \
  --header "Authorization: Bearer <your-token>"
```

**Connection timeout** — Increase the MCP startup timeout:

```bash
MCP_TIMEOUT=30000 claude
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.controltheory.com/controltheory-documentation/dstl8-docs/mcp-integration/claude-code.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
