How to Use the Loom (Async Video Messaging) MCP in Pydantic AI

Q: How do I connect Loom (Async Video Messaging) to Pydantic AI?

Install the pydantic-ai-slimmcp package. Instantiate MCPToolset with your Vinkius HTTP endpoint, and pass it directly to your Agent's MCP toolsets parameter.

Q: Can I run Pydantic AI validation on Loom workspace folders?

Yes. When calling listfolders, the returned folder structures are parsed and validated against internal Pydantic models to ensure strict schema compliance.

Build type-safe video automation pipelines using Pydantic AI to validate every Loom response.

Perplexity

Validate video metadata at runtime

The `get_video` tool retrieves detailed video payloads that Pydantic AI immediately validates against strict runtime schemas. This guarantees that your agent never operates on corrupted or incomplete metadata. If Loom's API returns unexpected fields, the framework fails loudly before any downstream code executes. This strict type-safety prevents silent failures in your production automation.

Parse transcripts safely with this MCP Server

You use `get_transcript` to extract raw text data from your video messages. The framework validates the string output, ensuring your LLM receives clean, structured data every time. Because Pydantic AI is model-agnostic, you can route these validated transcripts to OpenAI, Anthropic, or local models. The MCP validation layer remains identical, protecting your prompt templates from formatting errors.

Maintain clean workspaces with type-safe tools

The `list_videos` tool returns a structured list of all video records in your workspace. Your agent filters this list, then calls `update_video` to correct titles or `delete_video` to remove old files. Every response from these actions is validated at runtime. This ensures that your workspace cleanup scripts run with zero data corruption or unhandled API exceptions.

Setup guide

Set up Loom (Async Video Messaging) MCP in Pydantic AI

Prerequisites

Python 3.10+ installed
pydantic-ai-slim[fastmcp] package
Active Vinkius subscription with a valid endpoint token

1

Install Pydantic AI with FastMCP
Run pip install "pydantic-ai-slim[fastmcp]". The FastMCP toolset replaces the deprecated MCPServerHTTP class with full protocol support.
2

Configure the FastMCPToolset
Pass a JSON-style config dict to FastMCPToolset with your Vinkius URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. Supports Streamable HTTP, SSE, and Stdio transports.
3

Create and run your agent
Pass the toolset to Agent(toolsets=[toolset]) and call agent.run(). Swap openai:gpt-4o for any supported model — Anthropic, Google, Mistral, or Groq.

agent.py

from pydantic_ai import Agent
from pydantic_ai.toolsets.fastmcp import FastMCPToolset

toolset = FastMCPToolset({
    "mcpServers": {
        "loom-async-video-messaging-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to Loom (Async Video Messaging) tools.",
)

result = await agent.run("List recent Loom (Async Video Messaging) transactions")
print(result.output)

Common questions about Loom (Async Video Messaging) MCP in Pydantic AI

Install the `pydantic-ai-slim[mcp]` package. Instantiate `MCPToolset` with your Vinkius HTTP endpoint, and pass it directly to your Agent's MCP toolsets parameter.

The framework raises a validation error immediately. It halts execution before your agent can act on malformed video metadata or corrupt transcripts, preventing silent failures.

The framework supports both Streamable HTTP and SSE transports. You connect directly to your managed Vinkius endpoint using the unified `MCPToolset` class.

Yes. When calling `list_folders`, the returned folder structures are parsed and validated against internal Pydantic models to ensure strict schema compliance.

No. The MCP server operates as an ephemeral proxy in an isolated V8 sandbox. Your video titles, transcripts, and member lists are processed in-memory and never written to persistent storage.
