## Introduction

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows.
This guide explains the easiest and most robust way to connect your ConfigCat account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

- [Claude Cowork](https://composio.dev/toolkits/configcat/framework/claude-cowork)

## TL;DR

### What is Composio Connect?
Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness — including Hermes. It can:
- Search and load tools from relevant toolkits on-demand, reducing context usage.
- Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
- Manage app authentication end-to-end with zero manual overhead.

## Connect ConfigCat to Hermes

### Integrating ConfigCat with Hermes
### Using Composio Connect CLI
1. Install the Composio CLI
Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

```bash
curl -fsSL https://composio.dev/install | bash
```

## What is the ConfigCat MCP server, and what's possible with it?

The ConfigCat MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your ConfigCat account. It provides structured and secure access so your agent can perform ConfigCat operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CONFIGCAT_CREATE_SETTING` | Create Flag or Setting | Create a feature flag or typed setting in a Config. The key must be unique within that Config. |
| `CONFIGCAT_DELETE_SETTING` | Delete Flag or Setting | Permanently delete one ConfigCat feature flag or setting by ID. This cannot be undone; verify the setting ID before calling. |
| `CONFIGCAT_GET_PRODUCT_CONTEXT` | Get Product Context | Return a ConfigCat Product's configs, environments, segments, and tags, including the identifiers and evaluation versions needed to manage flags and targeting. |
| `CONFIGCAT_GET_SETTING_VALUE_V2` | Get Environment Setting Value V2 | Get one Config V2 flag or setting's complete evaluation formula in an Environment, including its optimistic-concurrency version. |
| `CONFIGCAT_LIST_ACCOUNT_HIERARCHY` | List Account Hierarchy | List accessible ConfigCat organizations and products so an agent can resolve the IDs needed by product-scoped tools. |
| `CONFIGCAT_LIST_ENVIRONMENT_VALUES_V2` | List Environment Values V2 | Return every Config V2 feature flag and setting evaluation formula for one Config and Environment, preserving ordered targeting rules and concurrency versions while omitting parent objects and updater data. |
| `CONFIGCAT_LIST_SETTINGS` | List Flags and Settings | List feature flags and settings in one Config, including IDs, keys, types, tags, and metadata needed by value operations. |
| `CONFIGCAT_PATCH_SETTING_VALUE_V2` | Patch Environment Setting Value V2 | Update selected typed fields of one Config V2 evaluation formula while preserving every field the caller omits. |
| `CONFIGCAT_REPLACE_SETTING_VALUE_V2` | Replace Environment Setting Value V2 | Completely replace one Config V2 flag or setting evaluation formula in an Environment. Supply the complete default value, ordered targeting rules, and percentage attribute; omitted state is intentionally reset. |
| `CONFIGCAT_UPDATE_SETTING_METADATA` | Update Flag Metadata | Partially update a flag or setting's name, hint, or complete tag assignment without resetting untouched metadata. |

## Creating MCP Server - Stand-alone vs Composio SDK

The ConfigCat MCP server provides comprehensive access to ConfigCat operations through Composio. Once connected, Hermes can perform all major ConfigCat actions on your behalf using natural language commands.

## Complete Code

## Conclusion

### Way Forward
With ConfigCat connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.
From here, you can extend Hermes further:
- Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
- Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
- Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and ConfigCat MCP?

With a standalone ConfigCat MCP server, the agents and LLMs can only access a fixed set of ConfigCat tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from ConfigCat and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Hermes?

Yes, you can. Hermes fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right ConfigCat tools.

### Can I manage the permissions and scopes for ConfigCat while using Tool Router?

Yes, absolutely. You can configure which ConfigCat scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your ConfigCat data and credentials are handled as safely as possible.
