Grain MCP Server

Overview

The Grain MCP Server bridges the gap between AI assistants and Grain, a meeting‑recording platform that captures audio, video, and live transcriptions. By exposing Grain’s core features through the Model Context Protocol, it removes the need for paid enterprise APIs or third‑party integration services such as Zapier. Developers can now query, retrieve, and download meeting data directly from an AI assistant, making the workflow seamless for teams that rely on Grain to store and review conversations.

At its core, the server uses browser automation (Playwright) to log into Grain and interact with the web interface. Once authenticated, two primary tools are available:

• – pulls a list of all meetings, including identifiers, titles, URLs, and timestamps.
• – fetches a transcript file for a specific meeting in either VTT or SRT format, saving it to a path supplied by the client.

These tools are designed to be invoked via natural language prompts. For example, a user can ask the assistant for “all recent meetings” or to “download the transcript of my last team meeting,” and the assistant will automatically translate that request into a tool call, execute it on the server, and return the results.

Why It Matters for AI Workflows

• Unified Data Access: Developers can treat Grain data as a first‑class resource in their AI pipelines, enabling tasks such as summarization, sentiment analysis, or compliance monitoring without leaving the assistant environment.
• Cost Efficiency: By leveraging browser automation instead of paid APIs, organizations can keep integration costs low while still providing rich meeting insights to their AI agents.
• Rapid Prototyping: The MCP interface allows quick experimentation—adding new prompts or chaining tools—without modifying Grain’s backend.
• Security & Privacy: All interactions happen through the user’s own Grain session, so sensitive meeting content remains within the existing authentication context.

Real‑World Use Cases

1. Automated Meeting Summaries – An assistant can fetch all meetings from the past week, download each transcript, and generate concise summaries that are emailed to stakeholders.
2. Compliance Audits – Legal teams can request transcripts for specific dates or topics, allowing auditors to verify that conversations meet regulatory standards.
3. Knowledge Management – Transcripts can be ingested into a company knowledge base, indexed by topic or participant, and queried through the assistant.
4. Product Feedback Loops – Customer success managers can retrieve and analyze transcripts of client calls to surface recurring pain points, feeding insights back into product roadmaps.

Standout Advantages

• Zero‑API Dependency: Works with any Grain subscription, sidestepping the limitations of enterprise‑only APIs.
• MCP‑Native Integration: The server follows the Model Context Protocol’s conventions, ensuring compatibility with any MCP‑compliant client.
• Browser‑Based Automation: By mirroring the web experience, it remains resilient to API changes and supports all features available in Grain’s UI.

In summary, the Grain MCP Server empowers developers to harness meeting data directly within AI assistants, delivering a cost‑effective, secure, and flexible bridge between Grain’s rich conversational records and the next generation of intelligent workflows.
