Connections are added inside an Access bundle. At claude.ai/admin-settings/claude-tag, open Access bundles in the left navigation, click into a bundle (or Create one), and go to its Credentials tab.
Connecting Sentry lets Claude pull errors and stack traces into incident threads from any channel under the bundle’s scope. You add it as a connection inside an Access bundle; the credential belongs to the agent, not to any person. Pair this connection with the Sentry plugin from Anthropic’s plugin marketplace so Claude knows how to call the API; see Attach plugins. This is an HTTP API connection, not an MCP server or a personal claude.ai connector.

​
Create the credential in Sentry

Create an internal-integration token in Sentry (Settings → Developer Settings → Internal Integrations) rather than a user auth token; scope it to the projects Claude should read. The token starts with sntrys_. Prefer an internal-integration token over a user auth token so access is not tied to a person. Sentry’s own guide for creating the credential is at docs.sentry.io.

​
Add the connection to a bundle

In the bundle, click Connect next to Sentry.

Allowed websitessentry.io
Self-hosted Sentry uses your own hostname instead of sentry.io. The Agent Proxy injects the credential at the network boundary; the model and the sandbox are not given the key. See how Agent Proxy works.

​
Verify the connection

In a channel under the bundle’s scope, in a new thread: 
@Claude what can you access from this channel?
Sentry appears in the list once the connection is live. New connections apply to new threads only.
