Fathom

Overview

The Fathom MCP lets agents access your Fathom meeting data without leaving the conversation. It supports:

Listing meetings with powerful filters (date range, teams, recorded by, domains)
Optionally including AI summary, action items, and CRM matches in the meeting results
Retrieving the full transcript for a specific recording

This connector is read-only and designed for safe retrieval of meeting context.

Connection Setup (Admin)

In Dust, go to Spaces → Tools and click Add Tools.
Select Fathom from the list of available tools.
Complete the OAuth flow to connect your Fathom account.
Choose whether to use Shared (workspace) or Personal credentials based on your policy.
Share the tool to the spaces where you want it available.

Once connected, the Fathom toolset will be available to add to agents in the spaces you grant access to.

Authentication

Fathom uses OAuth. An admin must complete the initial OAuth flow during setup. You can then operate with either:

Shared credentials — all users share the same connection.
Personal credentials — each user authenticates the first time they use the tool.

Choose based on your organization's security model. See Personal vs Shared Credentials for guidance.

Adding Fathom Tools to Agents

After admin setup, the Fathom toolset can be added to an agent by selecting it in the Agent Builder. Admins can make it available to specific spaces or organization-wide.

Tips

Find a specific call: Use recording_id with include_summary: true in list_meetings to fetch a single meeting's metadata and summary, then call get_transcript for the full text.
Large transcripts: Results are saved as files. Open the transcript file and scroll or load progressively. For programmatic reads, use chunked reads.

Troubleshooting

Authentication prompts keep appearing: If using Personal credentials, each user must authenticate on first use. Admins should complete the initial OAuth flow during setup.
Tool not visible in a space: Confirm the Fathom tool is shared with that space under the tool's Sharing tab.
