## How to Develop
Install and build:
```
npm install
npm run build
```
Run your local installation from Claude Code:
```
{
"mcpServers": {
"rollbar": {
"type": "stdio",
"command": "node",
"args": [
"/ABSOLUTE/PATH/TO/rollbar-mcp-server/build/index.js"
],
"env": {
"ROLLBAR_ACCESS_TOKEN": "<project read/write access token>"
}
}
}
}
```
Add `ROLLBAR_API_BASE` to the `env` map if you need to point the server at a custom Rollbar API endpoint (for example, `"ROLLBAR_API_BASE": "https://rollbar-dev.example.com/api/1"`).
Run your local installation from VSCode:
```
{
"servers": {
"rollbar": {
"type": "stdio",
"command": "node",
"args": [
"/ABSOLUTE/PATH/TO/rollbar-mcp-server/build/index.js"
],
"env": {
"ROLLBAR_ACCESS_TOKEN": "<project read/write access token>"
}
}
}
}
```
You can test an individual tool using the `@modelcontextprotocol/inspector` module. For example, test the tool `get-item-details` with arg `counter=2455389`:
```
npx @modelcontextprotocol/inspector --cli -e ROLLBAR_ACCESS_TOKEN=$TOKEN node build/index.js --method tools/call --tool-name get-item-details --tool-arg counter=2455389 --debug
```
To run the e2e tests, you'll need a read token in the env var ROLLBAR_E2E_READ_TOKEN, which should be a read-scope project access token for a Rollbar project that has items inside, including an item with counter #8.
