Ship an MCP from your API in minutes
Expose your API, OpenAPI specs and docs as a production MCP server. Ship agent-native tools without writing glue code.
Stop hand-rolling MCP servers for every repo and API.
Most teams that adopt MCP start the same way: a weekend prototype, a handful of tools wired by hand, then a growing pile of glue code every time the OpenAPI spec or docs change. InstantMCP.io is built for that exact pain.
Point us at your public API, OpenAPI document, SDK docs, or GitHub repo. We extract resources and tools, generate a production MCP server, and give you a hosted endpoint you can plug into Claude, Cursor, ChatGPT, or any MCP-compatible client, without maintaining a separate service just for agents.
When your schema evolves, refresh the source. Versions stay tracked, rollbacks stay one click away, and you keep shipping product instead of babysitting adapter code. Power users can still customize tool definitions and prompts; everyone else gets a working server on day one.
Whether you are exposing an internal platform API to your own agents or making your SaaS agent-native for customers, InstantMCP.io turns “we should build an MCP” into a mergeable URL.
The pieces you would have written yourself. Already shipped.
Skip the boilerplate. Keep control where it matters: auth boundaries, tool naming, and what agents are allowed to call.
From OpenAPI to tools
Map paths and schemas into callable MCP tools so agents interact with your API the way your clients already do.
Inspect before you ship
Preview generated tools, test calls, and iterate on descriptions before anything hits production clients.
Stay in sync
Re-run ingestion when docs or specs change. Optional webhooks keep your MCP aligned with the source of truth.
From repo to agent-ready in one afternoon
A concrete loop you can run on a side project, then promote to production.
- 01
Connect a source
Paste an OpenAPI URL, docs site, or point InstantMCP.io at a GitHub repo.
- 02
Review the tools
Check generated tools and resources. Tweak names and descriptions if needed.
- 03
Get the endpoint
Copy the hosted MCP URL into Claude Desktop, Cursor, or your agent harness.
- 04
Iterate safely
Ship a new version when the API changes. Roll back if a tool regresses.
Three steps. Zero code.
Connect a source
Drop a URL, upload docs, or sync a repo. We support websites, PDFs, Markdown, Notion, OpenAPI and more.
We generate the MCP
Our pipeline extracts structure, defines tools and resources, and writes the MCP server for you.
Ship it everywhere
Get a hosted endpoint instantly. Plug it into Claude, Cursor, ChatGPT or any MCP client.
Ultraweight optimized MCPs
InstantMCP.io does not wrap your whole API in a generic wrapper. It ships a small, focused server so agents respond quickly and stay useful.
Runtime
Lean by default
Only the tools an agent needs. Descriptions stay short. Payloads stay small.
Go-live
Endpoint ready
Hosted URL as soon as generation completes. Plug it into Claude, Cursor, or ChatGPT.
Agent loop
Quick + on-brief
Cached reads, tight schemas, fewer wasted tool calls. Users feel the difference.
Optimized code
Generated servers stay lean: tight tool schemas, no unused endpoints, handlers that do one job. Less noise for the model, fewer tokens wasted.
Deploy in seconds
Generation finishes, the hosted endpoint is live. Caching and scale are already there. No container to babysit, no weekend infra project.
Fast, accurate replies
Agents hit focused tools and cached resources, not a bloated dump of your docs. Round-trips stay short. Answers stay on the question.
One endpoint, every MCP client. Connect your server anywhere the protocol is supported.
Questions, answered.
MCP (Model Context Protocol) is an open standard from Anthropic that lets AI clients like Claude, Cursor and ChatGPT connect to external tools and data in a structured way.
