How to integrate Human Approval - HITL Platform MCP with Hermes

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 Human Approval - HITL Platform 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.

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.

Integrating Human Approval - HITL Platform 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
Hermes authenticating with Composio

2. Authenticate

Once the CLI is installed, ask Hermes to authenticate with Composio.

3. Connect to Human Approval - HITL Platform

Ask your agent to connect to Human Approval - HITL Platform, or simply request any Human Approval - HITL Platform-related task. Hermes will prompt you to authenticate and authorize access.

4. Done. You're all set with a new Human Approval - HITL Platform connection.


Using Composio Connect MCP

1. Get your MCP URL and API Key

Go to dashboard.composio.dev and copy your Connect MCP URL and API key.

Copy MCP URL and API key from Composio dashboard

2. Open the Hermes config file

bash
nano ~/.hermes/config.yaml

3. Add the Composio Connect MCP server

bash
mcp_servers:
  composio:
    url: "https://connect.composio.dev/mcp"
    headers:
      x-consumer-api-key: "YOUR_COMPOSIO_API_KEY"
    connect_timeout: 60
    timeout: 180

Save with Ctrl + O, Enter, then exit with Ctrl + X.

4. Restart your Hermes agent

Once restarted, ask your agent to connect to Human Approval - HITL Platform or request any Human Approval - HITL Platform-related task. It will prompt you to authenticate and authorize access.

5. Done!

What is the Human Approval - HITL Platform MCP server, and what's possible with it?

The Human Approval - HITL Platform MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Human Approval - HITL Platform account. It provides structured and secure access to your human approval loops and review requests, so your agent can organize reviewers, request decisions, track responses, cancel pending reviews, and manage approval loops on your behalf.

  • Approval loop management: Have your agent create, rename, describe, list, or permanently delete approval loops for different teams and workflows.
  • Reviewer readiness checks: Let the agent list active and pending reviewers in a loop before sending work for human approval.
  • Human approval requests: Direct your agent to create and broadcast structured approval requests to the active reviewers in a chosen loop.
  • Decision tracking and cancellation: Instruct your agent to check an approval request's status and human response, list previous requests, or cancel a pending request.
  • Account and allowance checks: Have your agent verify the connected account's status, permissions, and remaining request allowance before asking for approval.

Way Forward

With Human Approval - HITL Platform 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.

TOOLS

Supported Tools

Every Human Approval - HITL Platform action and event your agent gets out of the box.

Cancel Approval Request

Irreversibly cancel a pending approval request so reviewers can no longer complete it.

Create Approval Request

Create and broadcast one human approval request to active members of an owned loop, consuming one provider request allowance.

Create Loop

Create an approval loop and return its loop ID and human invitation links; the connected account is added as an active member.

Delete Loop

Permanently delete an owned loop and all of its memberships, approval requests, responses, feedback, and analytics.

Get Account Status

Return the connected HITL account identity, status, permissions, and provider-reported request allowance before creating an approval request.

Get Approval Request

Get the current status, configuration, and human response for one approval request; use for deliberate polling after creation.

List Approval Requests

Return approval requests created by the connected API key, optionally restricted to one loop; pagination controls are omitted because the live API currently ignores them.

List Loop Members

Return a loop's active and pending human reviewers so an agent can verify readiness before broadcasting an approval request.

List Loops

Return all approval loops owned by the connected account, including embedded members and membership counts.

Update Loop

Update one or more display fields of an owned approval loop without changing its members or requests.

FAQ

Frequently asked questions

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

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 Human Approval - HITL Platform tools.

Yes, absolutely. You can configure which Human Approval - HITL Platform 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.

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 Human Approval - HITL Platform data and credentials are handled as safely as possible.
