This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Honcho account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Honcho with - [ChatGPT](https://composio.dev/toolkits/honcho/framework/chatgpt) - [Claude Cowork](https://composio.dev/toolkits/honcho/framework/claude-cowork) - [Hermes](https://composio.dev/toolkits/honcho/framework/hermes-agent) ## TL;DR ### How Atomic Agent connects to Honcho Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication. Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account. ## Connect Honcho to Atomic Agent ### Connect Honcho to Atomic Agent - Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key. - In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart. - Ask Atomic Agent to do something in Honcho. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Honcho account, then return to Atomic Agent to continue. ### Headless setup Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file. ```bash COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY ``` ## What is the Honcho MCP server, and what's possible with it? The Honcho MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Honcho account. It provides structured and secure access so your agent can perform Honcho operations on your behalf. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `HONCHO_CHAT_WITH_PEER` | Chat With Peer | Run usage-bearing agentic search and reasoning over a peer's learned representation to answer a question. Higher reasoning levels generally cost more and take longer. Returns one non-streaming JSON response. | | `HONCHO_CREATE_CONCLUSIONS` | Create Conclusions | Store a batch of 1-100 explicit conclusions about peers, optionally tied to sessions. | | `HONCHO_CREATE_MESSAGES` | Create Messages | Add a batch of 1-100 attributed messages to a Honcho session. Message-level reasoning settings can trigger usage-bearing processing. | | `HONCHO_DELETE_SESSION` | Delete Session | Permanently delete one known session and its session-scoped data. Honcho marks the session inactive immediately and completes deletion asynchronously. | | `HONCHO_GET_MESSAGE` | Get Message | Return one message by its exact ID within a session. | | `HONCHO_GET_OR_CREATE_PEER` | Get or Create Peer | Return a peer by ID within a workspace, creating it with the supplied metadata and configuration when absent. Existing peers are returned unchanged. | | `HONCHO_GET_OR_CREATE_SESSION` | Get or Create Session | Return a session by ID, or create it with initial peers, metadata, and configuration when absent. Creation may create missing peers and start usage-bearing processing when reasoning features are enabled; existing sessions remain unchanged. | | `HONCHO_GET_OR_CREATE_WORKSPACE` | Get or Create Workspace | Return a workspace by ID, or create it with metadata and configuration when absent. Enabling reasoning features during creation may start usage-bearing background processing. | | `HONCHO_GET_PEER_REPRESENTATION` | Get Peer Representation | Return a curated subset of conclusions representing a peer. Supplying search_query performs semantic retrieval and may consume paid search capacity; omit it for the existing default representation. | | `HONCHO_LIST_CONCLUSIONS` | List Conclusions | Return one page of stored conclusions in a workspace; use Search Conclusions for semantic retrieval. | | `HONCHO_LIST_MESSAGES` | List Messages | Return one page of messages in a session; use Get Message for exact-ID retrieval. | | `HONCHO_LIST_PEERS` | List Peers | Return one page of peers in a workspace. | | `HONCHO_LIST_SESSIONS` | List Sessions | Return one page of sessions in a workspace. | | `HONCHO_LIST_WORKSPACES` | List Workspaces | Return one page of Honcho workspaces visible to the connected admin key. | | `HONCHO_SEARCH_CONCLUSIONS` | Search Conclusions | Semantically search stored conclusions in a workspace. This operation may consume paid search or embedding capacity; use List Conclusions to browse stored conclusions without semantic retrieval. | | `HONCHO_SEARCH_MESSAGES` | Search Messages | Semantically search messages at workspace, peer, or session scope. WARNING: this operation may consume paid search or embedding capacity; use list or get message tools for exact or chronological retrieval. | ## Supported Triggers None listed. ## Troubleshooting ### Why is my API key rejected? Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying. ### Why are Composio tools unavailable after saving a key? Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk. ### Does Composio have a free plan? The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection. ## Complete Code None listed. ## Conclusion ### Use Honcho from Atomic Agent With your account connected, ask Atomic Agent to work with Honcho in natural language. You can connect more apps through the same Composio integration as you need them.

With a standalone Honcho MCP server, the agents and LLMs can only access a fixed set of Honcho tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Honcho and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Atomic Agent? Yes, you can. Atomic Agent 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 Honcho tools. ### Can I manage the permissions and scopes for Honcho while using Tool Router? Yes, absolutely. You can configure which Honcho 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 Honcho data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
