Overview

Description from the maker (original English)

Apache Camel API Gateway with REST-to-MCP bridging for LLM agents.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Search & AI memory

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

        "--rm",
        "docker.io/surisoft/capi-core:1.417.5"
      ]
    }
  }
}

Run this in your terminal

claude mcp add capi-core -- docker run -i --rm docker.io/surisoft/capi-core:1.417.5

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{

      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "capi-core": {
      "type": "stdio",
      "command": "docker",
      "args": [

        "--rm",
        "docker.io/surisoft/capi-core:1.417.5"
      ]
    }
  }

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is CAPI Gateway safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

CAPI Gateway

_Lightweight API Gateway_

CAPI is a lightweight API Gateway and load balancer built on Undertow's async proxy architecture. Services register themselves in HashiCorp Consul, and CAPI automatically discovers them, creates proxy handlers, and applies security, throttling, and observability policies — no database required.

Features

  • REST, WebSocket, and SSE gateway with fully async proxying (zero threads blocked during backend calls)
  • Service discovery via HashiCorp Consul (automatic route creation and removal)
  • OAuth2 / OIDC token validation (multi-provider, cookie-based auth supported)
  • API Key authentication with per-key throttling (via Consul KV)
  • Fine-grained authorization via OPA (Open Policy Agent, async policy evaluation)
  • Distributed throttling (Hazelcast, with Kubernetes discovery)
  • Load balancing (Round Robin) and Failover
  • Distributed tracing (OpenTelemetry / OTLP)
  • Prometheus metrics
  • OpenAPI spec aggregation from upstream services
  • TLS termination and dynamic truststore management (via Consul KV hot-reload)
  • CORS management
  • Admin API with health, metrics, and route inspection
  • Multi-instance support (route targeting per CAPI instance)
  • Reverse proxy headers (X-Forwarded-*)
  • [Experimental] MCP Gateway — expose services as MCP tools for LLM agents (JSON-RPC 2.0 over Streamable HTTP)
  • [Experimental] gRPC Gateway — transparent HTTP/2 reverse proxy for gRPC services with header-based routing

REST-to-MCP Bridging

CAPI's MCP Gateway turns any existing REST API into an MCP tool — no code changes on your backends.

Register a service in Consul with MCP metadata, and LLM agents (Claude Desktop, Cursor, custom agents) can discover and invoke it immediately. Your REST services don't need to know anything about MCP, JSON-RPC, or tool schemas. CAPI handles the translation:

LLM Agent                          CAPI                          Your REST API

(unchanged) tools/list ──────────────► reads Consul metadata ◄────────────── returns tool catalog

tools/call ──────────────► extracts arguments {"name":"..."} POST /endpoint ──────────────► handles request wraps response ◄────────────── returns JSON ◄────────────── MCP-formatted result

CAPI also supports real MCP Server backends — services that already speak JSON-RPC 2.0. Register them with mcp-type: server and CAPI discovers their tools automatically via tools/list, then proxies tools/call requests transparently. Both REST and MCP Server backends are aggregated under one unified MCP endpoint.

Unlike dedicated MCP gateways that require all backends to be MCP Servers, CAPI bridges the gap between existing REST infrastructure and LLM-native protocols. See the MCP Gateway docs and the demo for a working example with both backend types.

Quickstart

CAPI requires the CAPI_CONFIG_FILE environment variable pointing to a valid configuration file.

Running from JAR
CAPI_CONFIG_FILE=config/config.yaml java -jar capi-core.jar
Running with Docker
docker run -p 8380:8380 -p 8381:8381 \

-v $(pwd)/config/config.yaml:/capi/config/config.yaml \ -e CAPI_CONFIG_FILE=/capi/config/config.yaml \ surisoft/capi-core

Running with Helm (Kubernetes)

A Helm chart is available in helm/capi-core/.

helm install capi-core helm/capi-core

With custom values

helm install capi-core helm/capi-core -f my-values.yaml

Enable SSL and truststore

helm install capi-core helm/capi-core \ --set capi.ssl.enabled=true \ --set capi.ssl.keystoreBase64= \ --set capi.ssl.password=changeit

See helm/capi-core/values.yaml for all available configuration options.
