Perplexity

Type-safe Kong Gateway operations

Every tool call like `create_plugin` or `update_service` is validated against your Pydantic models at runtime. If the agent proposes an invalid schema, the system stops it immediately. This prevents silent corruption of your gateway state. You get the benefits of agentic speed with the safety of static typing.

Deterministic gateway mutations

Use `create_consumer` and `delete_consumer` with guaranteed structure. The agent receives a clear validation error if it misses a required field. You no longer worry about hallucinated configuration parameters. The framework forces the agent to adhere to your defined gateway structure.

Reliable state introspection

The agent uses `get_route` and `get_upstream` to verify current settings before proposing changes. It treats the gateway as a source of truth. This workflow ensures the agent never operates on stale data. It's built for engineers who prioritize system correctness above all else.

Setup guide

Set up Kong Gateway 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": {
        "kong-gateway-mcp": {
            "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
        }
    }
})

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

result = await agent.run("List recent Kong Gateway transactions")
print(result.output)
