How to Use the Insomnia (Collaborative API Design) MCP in Pydantic AI

Q: How do I set up Insomnia (Collaborative API Design) with Pydantic AI?

Install the framework using pip install "pydantic-ai-slimmcp" and initialize MCPToolset with your Vinkius MCP Server endpoint. Pass the toolset as toolsets=toolset directly to your Agent constructor to give it access to tools like listprojects and listfiles.

Q: How do I inspect active branches using this integration?

Your agent calls listbranches to retrieve a structured list of branch names and statuses. Pydantic AI validates this payload against its internal models, allowing the agent to safely determine which branch is active.

Q: How are my Insomnia credentials and API collections secured?

All API collections and workspace metadata accessed via getfile are handled through Vinkius's secure, zero-trust infrastructure. The V8 Isolate Sandbox runs each request in an ephemeral environment, ensuring your authentication tokens are never stored or exposed to external networks.

Validate your Insomnia API designs at runtime with Pydantic AI's type-safe, fail-fast Python framework.

Type-Safe Schema Validation with Pydantic AI

The `get_file` tool delivers structured JSON payloads that Pydantic AI validates against strict Python models at runtime. If an API spec contains malformed JSON or unexpected fields, the framework raises a validation error instantly, preventing corrupt data from breaking downstream code generators. This MCP Server uses `list_files` to locate design documents within a workspace. Because every step is strictly typed, your agent won't hallucinate file paths or process invalid draft schemas, giving you complete confidence in automated pipeline steps.

Runtime Environment Auditing

The `list_environments` tool lets your agent pull environment variable counts and names, which Pydantic AI validates against your organization's deployment policies. If a developer accidentally exposes a secret key in a non-production environment, the agent catches it during runtime validation. By using the unified `MCPToolset` connection, you avoid deprecated HTTP wrappers. The agent queries environment structures cleanly, failing loudly if any variable configuration violates your predefined Pydantic models.

Branch and Collaborator Verification

The `list_branches` tool tracks active feature branches, allowing your Pydantic AI agent to verify that development branches match expected naming conventions. The agent can also list organization members using `list_collaborators` to ensure that active branches are only managed by authorized team members. If the collaborator data returned does not match your internal user schema, Pydantic AI blocks the workflow. This strict validation prevents untrusted contributors from pushing untested changes to your mock servers fetched via `list_mocks`.

Setup guide

Set up Insomnia (Collaborative API Design) 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": {
        "insomnia-collaborative-api-design-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

agent = Agent(
    "openai:gpt-4o",
    toolsets=[toolset],
    system_prompt="You have access to Insomnia (Collaborative API Design) tools.",
)

result = await agent.run("List recent Insomnia (Collaborative API Design) transactions")
print(result.output)
