Stoplight

What is the Stoplight MCP Server?

Integrate the industry-leading API design and documentation capabilities of Stoplight into your conversational AI workflows. Empower your engineering teams to explore workspaces, evaluate OpenAPI schemas, and audit API projects natively from their conversational assistant. Securely map your AI to your Stoplight workspace, enabling the orchestration of complex documentation tasks, project navigation, and architectural reviews naturally without switching contexts or opening complex dashboards.

What you can do

  • Workspace Exploration — Rapidly inspect top-level organizational containers invoking list_workspaces, and track operational changes programmatically leveraging list_workspace_activity.
  • Project Management — Audit your API documentation repositories cataloging initiatives securely using list_projects, and retrieve full visibility metadata invoking get_project_details.
  • Schema & Documentation Discovery — Dive deeply into specific documentation structures retrieving files, endpoints, and models leveraging list_project_nodes, and parse their raw text safely utilizing get_node_details.
  • Team & Governance — Map project ownership accurately and enforce governance metrics iteratively assigning roles retrieving authorized contributors naturally via list_workspace_members.

How it works

  1. Install the Stoplight MCP module securely authenticating it to your organizational AI interface.
  2. In the MCP configurations, provide your STOPLIGHT_WORKSPACE slug and a valid STOPLIGHT_TOKEN generated directly from your Stoplight workspace settings.
  3. Prompt the AI: "List the latest active endpoints from our 'core-billing-api' project and retrieve the detailed schema documentation for the processing node."

Who is this for?

  • API Architects — Accelerate API design reviews by instantly accessing endpoints and OpenAPI models naturally via your terminal without leaving your coding environment.
  • Technical Writers — Discover and organize large scale API documentation landscapes rapidly summarizing updates directly from recent workspace activity logs.
  • Backend Engineers — Resolve integration dependencies efficiently by querying endpoint models across independent Stoplight projects precisely and securely.

Why Pydantic AI?

Pydantic AI validates every Stoplight tool response against typed schemas, catching data inconsistencies at build time. Connect 7 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.

  • 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 Stoplight integration code

  • Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors

  • Dependency injection system cleanly separates your Stoplight connection logic from agent behavior for testable, maintainable code

FAQ

Frequently asked questions

01

Is the integration read-only?

Yes. All tools only read from your Stoplight workspace — projects, nodes, schemas, and activity logs. No modifications or deletions are possible through this integration.

02

What is the workspace slug?

It's the subdomain of your Stoplight URL. For example, if your workspace is at https://acme.stoplight.io, the slug is acme. You can find it in the address bar when logged in.

03

What data can the agent access?

Projects, workspace members, activity logs, and all project nodes (endpoints, models, articles). Each node's full content — including OpenAPI schemas — can be retrieved via get_node_details.

04

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.

05

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.

06

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your Stoplight MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
