HasMCP
Turn any OpenAPI or Swagger spec into a hosted remote MCP server without writing code.
HasMCP is worth a look if your APIs already have an OpenAPI 3.0/3.1 or Swagger spec and you want them callable by Claude Code, Cursor, or ChatGPT without hand-writing MCP wrappers. The JMESPath and Goja interceptor pair is the real differentiator — declarative pruning plus JavaScript PII scrubbing inside the proxy layer addresses token cost and privacy in one place. It is less suited to teams that need to own the full server stack or run on-prem without an Enterprise plan, and heavy call volumes can push you into pay-as-you-go overages. If you prefer running your own server, a hand-built MCP implementation gives more control; if you mainly need an LLM gateway rather than spec-to-tool

Skip HasMCP if you need to self-host the MCP server without an Enterprise plan, or your API has no OpenAPI/Swagger definition to import.
The free Hobby tier caps at 250 tool calls per month, which an active agent can burn through in days, pushing you onto pay-as-you-go overages.
The $0 Hobby tier and $24/mo Cloud Pro ($20/mo yearly) make HasMCP cheap for solo developers and small teams who just need a spec-to-MCP bridge; you're paying meaningfully less than assembling a managed gateway plus auth plus PII-scrubbing stack yourself. Enterprise pricing is custom and gates the on-premise hosting and SLAs that larger organizations tend to require. High-volume agent traffic is where the metered overages start to matter more than the headline subscription price.
In short
HasMCP — Turn any OpenAPI or Swagger spec into a hosted remote MCP server without writing code. Best for Developers exposing REST APIs to LLMs quickly without coding, AI agent builders using Claude Code, Cursor, or ChatGPT, Teams avoiding MCP spec maintenance and server infrastructure.

About HasMCP
HasMCP is a no-code MCP server framework and gateway that converts OpenAPI 3.0/3.1 and Swagger API definitions into LLM-ready Model Context Protocol tools. You import your spec through a GUI and get a hosted remote MCP server in seconds — no installation, no config files, no boilerplate. It is built for the "LLM-to-API" gap: HasMCP handles OAuth2 elicitation with just-in-time token exchange into an encrypted secret vault, applies a dual-engine interceptor layer (declarative JMESPath pruning plus a procedural Goja JavaScript engine) that strips unused fields and scrubs PII before data reaches the model context window, and adds automatic rate limiting, realtime logs, and telemetry. The vendor reports up to 95% token reduction on large responses and a "Wrapper Pattern" that exposes only search tools for very large toolsets, fetching schemas on demand so you avoid saturating the context window. MCP Composition lets you bridge multiple discrete MCP servers into a single capability surface, and tool-changed events keep connected clients in sync without server restarts or re-indexing. It works with standard MCP clients including Claude Code, Claude Desktop, Cursor IDE, Zed Editor, the Antigravity Platform, and ChatGPT Plus/Pro. It fits developers and teams who already have an OpenAPI spec and want agent access to those endpoints fast, with auth, privacy, and observability handled for them.
Behind the Verdict
HasMCP targets a specific, real problem: you have a REST API, you have an OpenAPI or Swagger definition for it, and you want an agent to call it. The product's answer is a GUI import that generates MCP tool schemas with parameter descriptions and type-safe payloads automatically, plus a hosted remote MCP server you don't maintain. The things that separate it from writing your own MCP wrapper are the operational pieces. OAuth2 elicitation implements the MCP auth lifecycle so your server can prompt the user for credentials and exchange tokens just-in-time, stored in an encrypted vault, without putting user keys into the model context window. The dual-engine interceptor system does two jobs: JMESPath handles declarative projection and filtering (the vendor cites pruning 100KB JSON responses down to a few hundred bytes, up to 95% token reduction), and the embedded Goja JavaScript engine handles stateful transformations and PII redaction in the proxy layer with no Node.js cold starts. On top of that sit automatic rate limiting, a streaming debug console, a payload inspector, and telemetry covering tool-call analytics, user governance, and token economics. MCP Composition is the other headliner — it merges multiple MCP servers into one capability surface, which matters when you're wiring several SaaS APIs into a multi-agent setup. The Wrapper Pattern similarly keeps enormous toolsets from flooding the context window by exposing only search tools and fetching full schemas on demand. Where it will frustrate you: if you want to control every layer of the server stack, or need on-premise hosting, that's gated behind the Enterprise tier — the Cloud Hobby Free tier and Cloud Pro run on managed hosting. Small projects are cheap or free, but high call volumes move you into pay-as-you-go overages, and the free tier's 250 tool calls per month runs out quickly once an agent is doing real work. Finally, the whole approach assumes a usable OpenAPI or Swagger definition exists; if your API is undocumented, there is nothing for HasMCP to convert.

Real-world workflow fit
Concrete scenarios for the personas HasMCP actually fits — and what changes day-one when you adopt it.
Import the OpenAPI 3.1 spec through the HasMCP GUI, generate the MCP tools, then connect the hosted remote server URL to Claude Desktop and run a query through the streaming debug console to confirm the tool call works.
Outcome: The API's endpoints are callable from Claude Desktop without writing a single line of wrapper code, and the debug console shows the request, the JMESPath pruning, and the upstream response.
Expose several internal service specs as MCP servers, use MCP Composition to merge them into one capability surface, store service API keys in the encrypted vault, and add a Goja interceptor that redacts emails and phone numbers from responses.
Outcome: Cursor sees one consolidated tool surface, credentials stay out of the model context, and PII is stripped in the proxy layer before any data reaches the LLM.
Import the vendor's OpenAPI definition, rely on OAuth2 elicitation so the agent prompts the user to authorize, exchange the token just-in-time into the vault, and use JMESPath to trim the vendor's verbose list responses down to the fields the agent needs.
Outcome: The agent can call the third-party API on the user's behalf without user keys ever entering the context window, and payload size drops substantially on every call.
Use Cases
- Convert a legacy REST API into MCP tools for Claude Desktop without writing code
- Expose internal microservices as MCP servers for Cursor IDE assistants
- Compose several SaaS APIs into one MCP surface for multi-agent systems
- Use JMESPath to prune 100KB JSON responses to a few hundred bytes of context
- Add third-party OAuth2 APIs to an MCP agent with just-in-time token exchange
- Redact PII with the Goja engine before responses hit the model context window
- Watch how agents call your APIs in real time via the streaming debug console
Limitations
- HasMCP requires a structured API definition — OpenAPI 3.0/3.1 or Swagger — to generate tools, so undocumented or gRPC-only APIs are out of scope.
- Managed cloud hosting is the default; the on-premise hosting option sits on the Enterprise plan, so teams that need to run the server themselves without that tier are constrained.
- Cloud Pro includes 100k tool calls and the Hobby tier only 250 per month, with pay-as-you-go overages beyond that, so sustained high agent traffic moves you onto metered billing.
- The no-code GUI that makes setup fast also limits how far you can tweak the underlying server implementation compared with a purpose-built MCP server you write and host yourself.

Setup time & first value
How long it actually takes to get something useful out of HasMCP — broken out by persona, not the marketing-page minute.
For a developer with a working OpenAPI or Swagger definition, first value is fast: import the spec in the GUI, generate the tools, and point an MCP client at the hosted remote server — the vendor frames this as live in seconds, and the 30-second demo on the homepage walks through exactly that flow. For a team adding auth and privacy, budget extra time to configure the OAuth2 elicitation flow and
Switching to or from HasMCP
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a hand-written custom MCP wrapper: import your OpenAPI spec into HasMCP and let it generate the tool schemas instead of maintaining them by hand.
- →From raw OpenAPI/Swagger endpoints: point HasMCP at the same spec and expose the endpoints as MCP tools to your existing Claude Code or Cursor setup.
- →From a self-managed MCP server: move the spec into HasMCP's managed cloud to drop deployment, auth, and rate-limiting maintenance.
- ↗To a self-hosted MCP server: export the same OpenAPI spec and rebuild the tool definitions yourself if you need full stack control.
- ↗To a general LLM gateway: move to a gateway product if your main need is routing and guardrails rather than spec-to-tool conversion.
- ↗To an Enterprise HasMCP plan: stay on HasMCP but upgrade if you need on-premise hosting or SLAs instead of migrating away.
