## Description

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Exceptionless MCP or direct API to submit project events, inspect error activity, read client configuration, and monitor app health through natural language.

## Summary

Exceptionless is an open-source error monitoring and event reporting service.
Use it to ingest project events and manage client configuration with one API key.

## Categories

- developer tools & devops

## Toolkit Details

- Tools: 4

## Images

- Logo: https://logos.composio.dev/api/exceptionless

## Authentication

- **Api Key**
  - Type: `api_key`
  - Description: Api Key authentication for Exceptionless.
  - Setup:
    - Configure Api Key credentials for Exceptionless.
    - Use the credentials when creating an auth config in Composio.

## Suggested Prompts

- Send checkout failure event to Exceptionless
- Report payment timeout error event
- Get Exceptionless client configuration details

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `EXCEPTIONLESS_CLOSE_SESSION` | 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. |
| `EXCEPTIONLESS_GET_CLIENT_CONFIGURATION` | 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. |
| `EXCEPTIONLESS_SUBMIT_EVENT` | 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. |
| `EXCEPTIONLESS_SUBMIT_SESSION_HEARTBEAT` | 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. |

## Installation and MCP Setup

### Path 1: SDK Installation

#### Path 1, Step 1: Install Composio

Install the Composio SDK, the OpenAI provider, and the OpenAI SDK
```python
pip install composio composio_openai openai
```

```typescript
npm install @composio/core @composio/openai openai
```

#### Path 1, Step 2: Create a Composio session

Initialize Composio with the OpenAI Responses provider and create a session scoped to Exceptionless
```python
import json
from openai import OpenAI
from composio import Composio
from composio_openai import OpenAIResponsesProvider

composio = Composio(provider=OpenAIResponsesProvider())
client = OpenAI()

session = composio.create(user_id="your-user-id", toolkits=["exceptionless"])
tools = session.tools()
```

```typescript
import OpenAI from "openai";
import { Composio } from "@composio/core";
import { OpenAIResponsesProvider } from "@composio/openai";

const composio = new Composio({ provider: new OpenAIResponsesProvider() });
const client = new OpenAI();

const session = await composio.create("your-user-id", { toolkits: ["exceptionless"] });
const tools = await session.tools();
```

#### Path 1, Step 3: Run Exceptionless tools with your agent

Send a request, execute the Exceptionless tool calls through the session, and print the final answer
```python
response = client.responses.create(
    model="gpt-5.6-sol",
    tools=tools,
    input=[{"role": "user", "content": "Submit a new Exceptionless error event for a failed checkout request"}],
)

while True:
    tool_calls = [o for o in response.output if o.type == "function_call"]
    if not tool_calls:
        break
    results = composio.provider.handle_tool_calls(response=response, session=session)
    response = client.responses.create(
        model="gpt-5.6-sol",
        tools=tools,
        previous_response_id=response.id,
        input=[
            {"type": "function_call_output", "call_id": call.call_id, "output": json.dumps(results[i])}
            for i, call in enumerate(tool_calls)
        ],
    )

print(response.output_text)
```

```typescript
let response = await client.responses.create({
  model: "gpt-5.6-sol",
  tools,
  input: [{ role: "user", content: "Submit a new Exceptionless error event for a failed checkout request" }],
});

while (response.output.some((o) => o.type === "function_call")) {
  const outputs = await composio.provider.handleToolCalls(session, response.output);
  response = await client.responses.create({
    model: "gpt-5.6-sol",
    tools,
    previous_response_id: response.id,
    input: outputs,
  });
}

console.log(response.output_text);
```

### Path 2: MCP Server Setup

#### Path 2, Step 1: Install Composio

Install the Composio SDK and your agent framework
```python
pip install composio claude-agent-sdk
```

```typescript
npm install @composio/core ai @ai-sdk/mcp @ai-sdk/openai
```

#### Path 2, Step 2: Create a session with MCP enabled

Create a session scoped to Exceptionless and read its MCP URL and headers
```python
from composio import Composio

composio = Composio()
session = composio.create(user_id="your-user-id", toolkits=["exceptionless"], mcp=True)
```

```typescript
import { Composio } from "@composio/core";

const composio = new Composio();
const { mcp } = await composio.create("your-user-id", {
  toolkits: ["exceptionless"],
  mcp: true,
});
```

#### Path 2, Step 3: Connect your agent to the MCP server

Pass the session's MCP URL and headers to your agent and run a Exceptionless request
```python
import asyncio
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions, AssistantMessage, TextBlock

options = ClaudeAgentOptions(
    mcp_servers={
        "composio": {
            "type": "http",
            "url": session.mcp.url,
            "headers": session.mcp.headers,
        }
    },
    system_prompt="You are a helpful assistant with access to Exceptionless tools.",
    tools=[],
    allowed_tools=["mcp__composio__*"],
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query("Submit a new Exceptionless error event for a failed checkout request")
        async for message in client.receive_response():
            if isinstance(message, AssistantMessage):
                for block in message.content:
                    if isinstance(block, TextBlock):
                        print(block.text)

asyncio.run(main())
```

```typescript
import { createMCPClient } from "@ai-sdk/mcp";
import { openai } from "@ai-sdk/openai";
import { generateText, stepCountIs } from "ai";

const client = await createMCPClient({
  transport: { type: "http", url: mcp.url, headers: mcp.headers },
});

const { text } = await generateText({
  model: openai("gpt-5.6-sol"),
  tools: await client.tools(),
  prompt: "Submit a new Exceptionless error event for a failed checkout request",
  stopWhen: stepCountIs(10),
});

console.log(text);
await client.close();
```

## Why Use Composio?

### 1. AI Native Exceptionless Integration

- Supports both Exceptionless MCP and direct API based integrations
- Structured, LLM-friendly schemas for reliable event ingestion and client configuration tasks
- Rich coverage for sending project-bound events and working with Exceptionless data without bespoke integration code

### 2. Managed Auth

- Secure API key handling so your agents don't need hard-coded Exceptionless credentials
- Central place to manage, scope, and revoke Exceptionless access
- Per user and per environment credentials for safer project-bound API usage

### 3. Agent Optimized Design

- Tools are tuned using real error and success rates to improve reliability over time
- Clear schemas help agents submit the right Exceptionless event payloads the first time
- Comprehensive execution logs so you always know what ran, when, and on whose behalf

### 4. Enterprise Grade Security

- Fine-grained RBAC so you control which agents and users can access Exceptionless
- Scoped, least privilege access to Exceptionless project resources
- Full audit trail of agent actions to support review and compliance
