Karada
Turn OpenAPI specs into production MCP servers
Karada.ai is a hosted platform and high-performance Go engine that auto-compiles OpenAPI 3.0/3.1 (and Swagger) specifications into native Model Context Protocol (MCP) servers, and multiplexes official marketplace MCP integrations behind a single unified gateway for AI clients like Cursor, Claude, OpenAI, Gemini, and Copilot.
Key Features
OpenAPI to Native Go MCP Compiler
Point Karada at any OpenAPI 3.0/3.1 or Swagger spec and it automatically parses routes into native Go MCP servers with Streamable HTTP transport, supporting 10,000+ concurrent streams with a stated 0.42ms p99 execution time.
Enhanced Gateway with karada_agent meta-tool
Instead of stuffing dozens of raw tool schemas into the client prompt (the page cites 18k tokens for 40+ schemas), the client calls a single meta-tool while Karada discovers tools and executes multi-step workflows server-side, claiming ~95% context savings and reduced schema hallucination.
Unified Multi-Gateway Hub (Multiplexer)
Connect internal tools and marketplace MCPs behind a single bearer-token endpoint, with isolated staging/production gateways and per-tool encrypted credential vaults (PKCE, Bearer auth).
Composable Plugin Pipeline
One-click middleware additions with zero backend code changes: token-bucket rate limiting, semantic caching (cited 94% hit rate on LLM calls), OAuth 2.0 PKCE, and OpenTelemetry.
Zero-Downtime Spec Sync
Point to raw spec URLs or CI/CD webhooks; spec changes are hot-reloaded and deployed (stated 84ms hot-reload) without restarting agent sessions.
Curated MCP Marketplace & Registry
Connect official pre-built marketplace MCP servers in one click, plus a private MCP registry, alongside your own compiled OpenAPI servers.
Managed Hosting with Git CI/CD
Automatic Git CI/CD, managed container hosting, global edge routing, and DDoS mitigation for deployed Go MCP servers.
How It Works
- 1
Compile a spec into an MCP server
Provide an OpenAPI 3.0/3.1 or Swagger spec URL; the AST extractor parses routes and generates a native Go MCP tool server (zero reflection, strict schema validation) hosted on Karada.
- 2
Connect AI clients
Attach Cursor, Claude Code, or autonomous agents to your Karada gateway over standard open MCP via Streamable HTTP.
- 3
Execute tools through the gateway
The client calls the gateway (or the single karada_agent meta-tool), and Karada routes execution to the right MCP servers server-side, handling credentials and multi-step workflows.
Pros & Cons
Pros
- Automates MCP server generation from OpenAPI/Swagger specs, eliminating hand-written MCP server code
- High-performance Go runtime with stated sub-millisecond p99 execution (0.42ms) and support for 10,000+ concurrent streams
- Meta-agent gateway pattern claims ~95% prompt context savings and fewer schema hallucinations compared to loading raw schemas
- Centralized control plane for testing tool executions, inspecting SSE streams, and managing API credentials
- One-click middleware (rate limiting, semantic caching, OAuth PKCE, OpenTelemetry) without code changes
- Free Hobby tier with 5 hosted servers and a generous 100k requests/month included
Cons
- Currently in public beta, which may mean API changes or stability risk for production workloads
- Server generation is Go-specific; teams wanting self-hosted output in other languages or full source export are not addressed on the page
- Migrating away may be non-trivial since hosting, gateways, and secret vaults are platform-managed
- Most advanced features (enhanced gateway, secret vault, RBAC, cold start prevention) require paid tiers starting at $19/month
- Monthly request and bandwidth quotas on lower tiers (e.g., 100k requests and 10 GB bandwidth on the free Hobby plan)
Who It's For
Best for
- API-owning teams that want to expose their REST APIs as AI agent tools quickly from an OpenAPI spec
- AI agent developers using Cursor, Claude Code, or autonomous agents who need one unified gateway for many MCP servers
- Engineering teams that want managed MCP hosting with CI/CD, secret vaults, and observability rather than self-hosting
- Builders prototyping MCP tools on a free tier before scaling to production traffic
Not ideal for
- Teams that need to self-host the generated MCP server code outside Karada's managed platform
- Projects without an OpenAPI/Swagger spec who only want to compile from other API description formats
- Organizations requiring SSO/SAML, dedicated VPC, or uptime SLAs on standard self-serve plans (these are Enterprise-only)
- Users seeking a free plan with unlimited gateways, RBAC, or the enhanced karada_agent gateway
Use Cases
- Turning existing REST APIs (defined by OpenAPI specs) into AI-callable MCP tools without writing MCP server code
- Multiplexing multiple official MCP servers (e.g., Stripe, PostgreSQL, GitHub) behind a single endpoint for Cursor or Claude Code
- Reducing prompt context bloat for AI agents working with many tool schemas
- Hosting and monitoring production MCP server infrastructure with edge routing, rate limiting, and secret management
- Keeping deployed MCP tools in sync with API changes via CI/CD webhooks and zero-downtime spec updates

FAQ
What does Karada do?
Karada is a platform and high-performance Go engine that auto-compiles OpenAPI 3.0/3.1 or Swagger specs into hosted native Go MCP servers, and lets you multiplex official marketplace MCP integrations behind one unified gateway for AI clients like Cursor, Claude, OpenAI, Gemini, and Copilot.
How fast is the spec-to-server compilation?
The page cites a 0.42ms p99 tool execution runtime for compiled tools and an 84ms hot-reload time when an updated spec is deployed via zero-downtime spec sync.
Which AI clients and agents are supported?
Karada states support for all leading AI assistants and agents via 100% standard open MCP, naming Claude, OpenAI, Gemini, Cursor, and Copilot.
Is there a free tier?
Yes. The Hobby plan is free forever and includes 5 hosted Go MCP servers, 1 standard passthrough gateway, automatic Git CI/CD, managed container hosting, 100k requests/month, and community Discord support.
How does Karada prevent prompt context bloat?
Instead of loading dozens of raw tool schemas into the client prompt, the client calls a single meta-tool (karada_agent) while Karada discovers tools and executes workflows server-side. The page claims ~95% context savings and reduced schema hallucination versus a standard gateway loading 40+ schemas (~18k tokens).
Can I connect official pre-built MCP servers or only my own specs?
Both. Karada offers a curated MCP marketplace for one-click connections to official integrations, and can compile your own OpenAPI 3.0/3.1 or Swagger specs into hosted Go MCP servers. Free plans are limited to public marketplace connections.
How are API keys and credentials handled?
Karada provides per-tool encrypted credential vaults within isolated staging and production gateways, with OAuth PKCE, Bearer auth, and dynamic token delegation supported through its middleware pipeline.
What middleware and security features are available?
One-click, hot-pluggable plugins include token-bucket rate limiting (e.g., 100 req/min), semantic caching, OAuth 2.0 PKCE, and OpenTelemetry; plans also include global edge routing and DDoS mitigation.
