Why teams choose Vinkius for MakePlans in Pydantic AI
The MakePlans MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 10 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in Pydantic AI only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

Frequently asked questions
Where do I find my API Key?
In your MakePlans account, go to Setup > Integrations > API. You must enable the API to see your key.
What is the Account Name?
It is the subdomain of your MakePlans URL (e.g., if your URL is https://mybiz.makeplans.com, the account name is 'mybiz').
Can I use the MakePlans MCP server for a public website?
The MCP server uses the Private API and requires an API key, so it is intended for internal or authenticated use rather than direct exposure to unauthenticated public users.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your MakePlans MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
