NEW: gRPC Support & MCP Composition Coming Soon

Turn any API into an
MCP Server in seconds.

The no-code bridge between your OpenAPI specs and LLM-ready tools. Optimize payloads, manage secrets, and handle OAuth2 without writing a single line of server code.

Core MCP Infrastructure

HasMCP is engineered to solve the "LLM-to-API" gap. We provide a hardened, zero-code environment to deploy Model Context Protocol (MCP) servers with enterprise requirements.

Automated OpenAPI Mapping

Instantly transform OpenAPI 3.0/3.1 and Swagger definitions into structured MCP tools. Our engine automatically generates tool schemas, parameter descriptions, and type-safe payloads so LLMs can consume your endpoints with 100% accuracy and zero manual boilerplate.

Native MCP Elicitation Auth

Solve the authentication barrier with OAuth2 Elicitation. HasMCP implements the Model Context Protocol auth lifecycle, allowing your server to dynamically prompt users for credentials. Securely exchange tokens just-in-time for API calls without ever exposing sensitive user keys to the model context window.

Context Window Optimization

Reduce LLM inference costs and latency. Use high-speed JMESPath filters to prune massive JSON responses or write Goja-powered JavaScript Interceptors to sanitize data. By stripping unnecessary fields, you reduce token consumption by up to 90%, ensuring your agents focus only on relevant data.

Real-time Dynamic Tooling

Enable agile agentic workflows with tool_changed event support. HasMCP monitors your underlying API health and schema changes, notifying connected LLMs of new capabilities or structural updates instantly. No server restarts or manual client re-indexing required for tool discovery.

Secure Secret & Proxy Mgmt

Centralize your API security. Manage environment variables, API keys, and proxy headers via an encrypted vault. HasMCP ensures that incoming headers are securely passed to your upstream SaaS endpoints while remaining completely invisible to the LLM agent layer.

gRPC & MCP Composition

Future-proof your architecture. We are currently developing native gRPC support for high-speed streaming and MCP Composition, allowing you to bridge multiple discrete MCP servers into a unified, intelligent API mesh for complex multi-agent reasoning.

Performance Stack

High-Throughput Interceptors

Standard API gateways add significant overhead. HasMCP uses a dual-engine approach to ensure your MCP servers are lightning-fast and token-efficient.

DECLARATIVE

JMESPath Pruning

For pure data projection and filtering, JMESPath is the gold standard. It provides a powerful query language for JSON with zero execution overhead. Prune massive 100KB responses down to a few hundred bytes of context-ready data in microseconds.

  • ✔ Zero-latency projection engine
  • ✔ Declarative multi-select & filtering
  • ✔ Industry-standard query syntax
JMESPath Query
query: "items[?active].{id: uuid, tag: metadata.label}"
// Result: Only active items projected
[{"uuid": "a1", "label": "prod"}, ...]
PROCEDURAL

Goja (JS) Logic

When your data needs complex mutations, stateful transformations, or conditional logic, use our embedded Goja engine. Write pure JavaScript that executes directly within the proxy context—no Node.js cold starts, just raw performance.

  • ✔ Pre-parsed `input` JSON variable access
  • ✔ Full JS syntax (via Goja engine)
  • ✔ Logic-driven payload manipulation
JS Interceptor
const output = {
  id: input.id,
  desc: input.text.slice(0, 20),
  isValid: true
};
return output;
