How to integrate Flatfile 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 Flatfile 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 Flatfile 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 Flatfile

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

4. Done. You're all set with a new Flatfile 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 Flatfile or request any Flatfile-related task. It will prompt you to authenticate and authorize access.

5. Done!

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

The Flatfile MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Flatfile account. It provides structured and secure access to your environments, spaces, workbooks, sheets, records, files, and jobs, so your agent can discover data workspaces, inspect sheets, read and edit records, track files, and monitor jobs on your behalf.

  • Workspace and workbook discovery: Have your agent find environments, search spaces, and list workbooks with their sheets before starting a data task.
  • Sheet inspection and record retrieval: Let the agent inspect sheet fields and record counts, then read records based on validity, field values, or search terms.
  • Record creation and updates: Direct your agent to add rows to a sheet or update existing records with corrected and transformed values.
  • Record cleanup: Instruct your agent to permanently delete selected records from a Flatfile sheet when they are no longer needed.
  • File and job monitoring: Have your agent list import or export files, check their processing status, and review job progress, results, and diagnostic details.

Way Forward

With Flatfile 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 Flatfile action and event your agent gets out of the box.

Delete Records

Permanently delete one to 100 explicitly identified records from one Flatfile sheet.

Get Job

Get detailed status, outcome, result, and diagnostic information for one Flatfile asynchronous job.

Get Sheet

Get one sheet's field configuration and record counts before reading or writing records.

Get Space

Get safe metadata for one Flatfile space without exposing transient access credentials or token-bearing guest links.

Insert Records

Insert one or more rows into a Flatfile sheet using simple field-key to value objects.

List Environments

List Flatfile environments visible to the connected environment secret key and return the IDs needed to find spaces.

List Files

Discover import or export files and their processing status, optionally within a Flatfile space.

List Jobs

Find asynchronous Flatfile jobs by environment, space, workbook, file, or parent job and inspect progress at a glance.

List Records

Read one page of records from a Flatfile sheet, optionally filtering by validity, field, record ID, search value, or FFQL expression.

List Spaces

Find Flatfile spaces by environment, text, namespace, archive state, or template status.

List Workbooks

List workbooks, optionally within a space, with their nested sheets so an agent can continue to sheet and record tasks.

Update Records

Update one or more existing Flatfile records by ID using simple field-key to value objects.

FAQ

Frequently asked questions

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

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