Your code → custom MCP tools
Start from a template in Dev Studio. Edit code, configure tools, test calls, and deploy before reviewing and publishing your listing.
Open Dev StudioBuild, test, and deploy with Dev Studio. Turn APIs, documents, and skills into MCP experiences, publish to the marketplace, and optionally monetize. Explore our directory to find tools for your next project—and help users find yours.
From your first tool to your next user: development tools, publishing, and discovery in one place. Your platform API key connects supported marketplace subscriptions—not arbitrary crawled servers.
Develop · Test · Publish · Get discovered
Go from an idea to tools people can use. Develop in Dev Studio, connect a REST API, or turn skills and documents into MCP resources. Test and review your work, then publish. Our directory helps people find tools and creators reach users.

Open Dev StudioYour API → MCP tools
Bring an OpenAPI or Swagger spec. Turn your existing API operations into tools an MCP client can call.
Connect a REST APIYour know-how → reusable instructions
Publish a Markdown skill. Eligible public/free skills can be selected and served through our Skills over MCP endpoint—not executed as code.
Publish a skillYour content → searchable knowledge
Upload documents and create an MCP knowledge source. Let AI clients search and retrieve relevant content through the platform.
Upload documentsFor creators & providers
Offer your MCP for free or choose a paid plan. Platform listings bring discovery, subscriber access, usage tracking, and billing together.
Paid listings require billing setup and Stripe Connect for payouts. Skills over MCP currently serves eligible public/free skill content only.
Already built an MCP?
Add your MCP endpoint or import a GitHub source in the listing flow. We attempt tool discovery; you review the result and publish when it’s ready.
Sign in and submit a source you’re authorized to publish. A repository link may need hosting or connection setup before its tools can be used.
One platform key. Clear access boundaries. Use your platform API key for supported marketplace subscriptions and the separate Skills over MCP endpoint. Crawled directory links alone do not grant platform-key access; provider authentication may still be required.
Set up Skills over MCPSkills over MCP
Select up to 20 public/free skill Markdown docs and load them in your AI client through a platform MCP endpoint, using your platform API key.
Your AI client follows the instructions. This endpoint serves docs, not scripts or model calls, and does not grant access to crawled MCP servers.
No document credits. No overage charges.
Explore every feature with mock data. No sign-up required.
Ready to try the real thing?

Turn your OpenAPI spec into tools for Claude, Cursor and other MCP clients. Preview the schemas, configure authentication, and publish when you’re ready. Your API stays yours.
Your API. A new interface.
01 / Define
A curated OpenAPI specification.
openapi.json
/users/users/{id}/ordersKeep your endpoints and business logic.
02 / Configure
The gateway between API and agent.
Tool definitions
Names and input schemas from your spec.
Access & authentication
Platform-key access and configured provider auth.
Request translation
Tool arguments become HTTP requests.
Review configuration before publishing.
03 / Connect
Claude, Cursor & compatible MCP clients.
list_users
limit?: number
get_user
id: string
list_orders
status?: string
Published tools appear as slug/toolName.
Animated above: spec → tool definitions
At call time: MCP client → gateway → your API → result
After publication, users enable access and create their platform key on the website. The spec defines the tools; provider credentials still need configuration.
Every path × method becomes a named MCP tool. operationId, summary, and parameter schemas carry through.
Review your API’s auth requirements and configure supported provider credentials. The gateway attaches them when translating tool calls.
Nested schemas are dereferenced. JSON and form-urlencoded bodies just work. No manual rewriting.
Upload them. We register an MCP on the marketplace. Others subscribe and ask through the same gateway — one key, no extra URL. Free to start.
API docs, runbooks, a contract. We index the text.
A published MCP with ask and list_documents. It shows on Browse.
Subscribe, paste the gateway into Cursor, ask slug/ask. That is the whole path.

Already have paying customers?
Your customers already pay you. List your API here and they reach it from Claude, Cursor or any MCP client — on their own key, on their existing plan, billed by you exactly as they are today.
You ask for one thing
Add a field to your listing: “Your API key”. Your subscriber fills it in once, on their dashboard.
Never as a tool argument — so it never lands in an agent’s transcript, and you never see anyone else’s.
You get it on every call
X-MCP-Market-Config:
{"api_key": "ak_live_..."}Read one header. That is the whole integration — no accounts to create, no plan logic, no webhooks. Your rate limits and tiers apply unchanged, because it is their key.
Selling to people who don’t have an account yet? List one plan per tier and we handle the subscription — we tell you who signed up, and when they leave.
Already have a server? List it. If not, use Dev Studio, REST → MCP, or documents. We handle discovery, keys, metering, and billing. Free or Pro — payouts via Stripe Connect.
