About Assembly MCP Server
Assembly
The Assembly MCP Server allows AI agents to interact with your Assembly platform data seamlessly.
Pydantic AI validates every Assembly tool response against typed schemas, catching data inconsistencies at build time. Connect 10 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
What you can do
- Retrieve clients, companies, and users.
- Access workspaces and CRM details.
- Manage notes and internal data.
The Assembly MCP Server exposes 10 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
All 10 Assembly tools available for Pydantic AI
When Pydantic AI connects to Assembly through Vinkius, your AI agent gets direct access to every tool listed below — spanning client-management, workspace-management, crm, and more. Every call is secured with network, filesystem, subprocess, and code evaluation entitlements inside a sandboxed runtime. Beyond a simple connection, you get a full AI Gateway with real-time visibility into agent activity, enterprise governance, and optimized token usage.

Why Use Pydantic AI with the Assembly MCP Server
Pydantic AI provides unique advantages when paired with Assembly through the Model Context Protocol.
Full type safety: every MCP tool response is validated against Pydantic models, catching data inconsistencies before they reach your application
Model-agnostic architecture. switch between OpenAI, Anthropic, or Gemini without changing your Assembly integration code
Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors
Dependency injection system cleanly separates your Assembly connection logic from agent behavior for testable, maintainable code
Assembly + Pydantic AI Use Cases
Practical scenarios where Pydantic AI combined with the Assembly MCP Server delivers measurable value.
Type-safe data pipelines: query Assembly with guaranteed response schemas, feeding validated data into downstream processing
API orchestration: chain multiple Assembly tool calls with Pydantic validation at each step to ensure data integrity end-to-end
Production monitoring: build validated alert agents that query Assembly and output structured, schema-compliant notifications
Testing and QA: use Pydantic AI's dependency injection to mock Assembly responses and write comprehensive agent tests
Example Prompts for Assembly in Pydantic AI
Ready-to-use prompts you can give your Pydantic AI agent to start working with Assembly immediately.
"List all clients in Assembly."
