For platform teams with proprietary or legacy APIs: mcpmake turns OpenAPI specs, Postman collections, HAR files, and reviewed captures into curated MCP servers you own. We're piloting reviewable maintenance PRs (private beta) that keep them current. Export and self-host the code, or run it on our managed HTTP runtime. Website input is an experimental preview.
$ mcpmake deploy stripe-api.yaml

}OpenAPI spec, HAR file, Postman collection, or reviewed capture. Website / URL input is an experimental preview.
mcpmake generates editable code you can export and self-host. Managed HTTP hosting is an optional validation-cohort add-on.
Copy the config snippet into Claude Desktop, Cursor, or any MCP client.
Reliability depends on what you bring, so we state the promise for each input up front — no experimental adapter is sold as production-grade.
| Input | Support level | What we promise |
|---|---|---|
| OpenAPI / Swagger | Supported | Deterministic generation, tests, diff, CI, and maintenance eligibility. |
| Postman | Supported with acceptance review | Human-reviewed schema/auth/tool curation plus explicit acceptance tests; incomplete examples can create gaps. |
| HAR | Supported with acceptance review | Human-reviewed schema/auth/tool curation plus explicit acceptance tests; incomplete examples can create gaps. |
| Live URL / network capture | Assisted beta | Useful for discovery and paid migration work; coverage depends on exercised traffic. |
| Website DOM / Playwright | Experimental | Demo, scaffold, or custom services work only; no general production or uptime promise. |
| Natural-language describe | Experimental | Demo, scaffold, or custom services work only; no general production or uptime promise. |
login(email, password) instead of generic click(selector). Powered by Playwright — an experimental, invite-only preview.server.json to the official MCP registry, so your server is discoverable.When your source API changes, mcpmake regenerates and opens a maintenance PR that explains the diff. You review and merge it — nothing is force-pushed to your default branch. Keeping owned servers current this way is the paid hypothesis we're validating this quarter with a small, invite-only cohort.
| Platform | Approach | Limitation |
|---|---|---|
| Composio | Pre-built integrations | No bring-your-own-spec |
| Speakeasy | SDK + MCP generation | Generation-focused; enterprise/upmarket pricing |
| Playwright MCP | Generic browser automation | AI rediscovers page structure every call |
| mcpmake | Curated owned code + done-for-you migration | Free to start. |
Generate MCP servers you own with the free, open-source CLI and self-host anywhere. When you'd rather not run them yourself, we do the migration and operate them for you. You always keep the code — you pay only for the work and the managed compute.
Done-for-you migration and commercial support around the open-source CLI — you always keep the code.
Done-for-you implementation
Backed by us
Prefer not to run it yourself? The Managed HTTP Runtime is a $49/month add-on (3 active HTTP targets) — invitation-only while we validate hosting with a small cohort. You always keep the code.
Start with a spec or migration conversation. You keep the generated code, and managed hosting remains optional.
