# Exceptionless MCP

Vendor: Exceptionless  
Category: developer-tools  
Auth: API_KEY  
Composio slug: `exceptionless`

Exceptionless provides one-project event ingestion and client configuration using a project-bound client API key.

## Tools

- **Close Session** — Close an active session in the Exceptionless project bound to the connected client API key. This records irreversible session-closure telemetry and returns only an acceptance confirmation.
- **Get Client Configuration** — Return the configuration for the single Exceptionless project bound to the connected client API key. Configuration values can contain sensitive project settings; request and expose them only when needed.
- **Submit Event** — Submit one structured telemetry event to the Exceptionless project bound to the connected client API key. Acceptance is asynchronous and does not confirm that the event was processed or persisted.
- **Submit Session Heartbeat** — Record an active session heartbeat in the Exceptionless project bound to the connected client API key. Use Close Session separately when the session ends. Despite using GET upstream, this tool writes telemetry.

## Setup

1. Create or open a Switchy Project.
2. Open Integrations and connect Exceptionless.
3. Authorise through api_key.
4. Teammates can now @-mention Exceptionless tools in chat.
