## 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 Common Room 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/common_room_mcp/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 Common Room MCP to Hermes

### Integrating Common Room 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 Common Room MCP server, and what's possible with it?

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

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `COMMON_ROOM_MCP_COMMONROOM_CREATE_OBJECT` | Commonroom create object | Writes a new contact, organization, segment, activity, note or tag to Common Room. Contacts and organizations are upserts, so this both creates and merges into an existing record; use commonroom_update_object instead when editing a record you have already identified. Look up the IDs and existing values it needs with commonroom_list_objects, and the writable fields for each type with commonroom_get_catalog. |
| `COMMON_ROOM_MCP_COMMONROOM_GET_CATALOG` | Commonroom get catalog | Reports which object types this workspace exposes and, for each, the fields it can be filtered by, the properties it can return, the fields it can be sorted by, and the other objects it is associated with. Call it before commonroom_list_objects, commonroom_create_object or commonroom_update_object: field names vary by workspace, so building a filter or a write from guessed names fails. |
| `COMMON_ROOM_MCP_COMMONROOM_LIST_OBJECTS` | Commonroom list objects | Reads Common Room records — contacts, organizations, activities, segments and custom objects — as a filtered, sorted, paginated list, or fetches one record by ID. Call commonroom_get_catalog first: it reports which object types exist and which fields each one can be filtered, sorted and returned by. Also use this tool to look up the values other filters expect, such as role names, Bombora topics and location IDs. Use commonroom_create_object or commonroom_update_object to write records; this tool only reads. |
| `COMMON_ROOM_MCP_COMMONROOM_SUBMIT_FEEDBACK` | Commonroom submit feedback | Records the user's verdict on results returned by a previous Common Room query. Call it after presenting data, when the user says the results were helpful, says they were wrong or incomplete, or comments on the data quality. It stores feedback only — it neither re-runs the query nor changes any record. |
| `COMMON_ROOM_MCP_COMMONROOM_UPDATE_OBJECT` | Commonroom update object | Edits an existing contact, organization, custom-object record or segment, identified by its ID. Every change is a partial update: omitted fields keep their current values and tag changes apply only to the tags listed. Use commonroom_create_object when the record may not exist yet, since that upserts contacts and organizations; use commonroom_list_objects to find the ID to pass here and commonroom_get_catalog for which fields are mutable. |

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

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

## Conclusion

### Way Forward
With Common Room 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 Common Room MCP?

With a standalone Common Room MCP server, the agents and LLMs can only access a fixed set of Common Room tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Common Room 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 Common Room tools.

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

Yes, absolutely. You can configure which Common Room 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 Common Room data and credentials are handled as safely as possible.
