Overview

Description from the maker (original English)

Self-healing proxy for MCP servers with retry, circuit breaker, and observability

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: Other

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).
  • You fill in yourself: SELFHEAL_CONFIG, SELFHEAL_MAX_RETRIES, SELFHEAL_CIRCUIT_THRESHOLD

You need

  • npmNode.js installed (for the npx command)

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

{
  "mcpServers": {
    "selfheal": {
      "command": "npx",
      "args": [
        "-y",
        "selfheal-mcp"
      ],
      "env": {
        "SELFHEAL_CONFIG": "your-value",
        "SELFHEAL_MAX_RETRIES": "your-value",
        "SELFHEAL_CIRCUIT_THRESHOLD": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add selfheal --env SELFHEAL_CONFIG=your-value --env SELFHEAL_MAX_RETRIES=your-value --env SELFHEAL_CIRCUIT_THRESHOLD=your-value -- npx -y selfheal-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "selfheal": {
      "command": "npx",
      "args": [
        "-y",
        "selfheal-mcp"
      ],
      "env": {
        "SELFHEAL_CONFIG": "your-value",
        "SELFHEAL_MAX_RETRIES": "your-value",
        "SELFHEAL_CIRCUIT_THRESHOLD": "your-value"
      }
    }
  }
}

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": {
    "selfheal": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "selfheal-mcp"
      ],
      "env": {
        "SELFHEAL_CONFIG": "your-value",
        "SELFHEAL_MAX_RETRIES": "your-value",
        "SELFHEAL_CIRCUIT_THRESHOLD": "your-value"
      }
    }
  }
}

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.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • SELFHEAL_CONFIG env
    Path to selfheal.config.json (optional, defaults to cwd)
  • SELFHEAL_MAX_RETRIES env
    Max retry attempts per call (default: 3)
  • SELFHEAL_CIRCUIT_THRESHOLD env
    Failures before circuit opens (default: 5)

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is SelfHeal MCP 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 (0.1.1) reached the registry 7 months ago.

Which apps can use it?

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

What can I use instead?

SelfHeal MCP

Self-healing proxy for MCP servers. Wraps any MCP tool call with automatic retry, circuit breaker protection, and call observability.

Your AI agents stop breaking on flaky APIs.

One-click install: Install on MCPize | npx selfheal-mcp

Features

  • Retry with backoff — Exponential backoff + jitter on transient failures (5xx, timeouts, rate limits)
  • Circuit breaker — Per-target circuit breaker stops hammering dead services
  • Call metrics — Success rates, latency, error frequency, broken down by tool and target
  • Proxy mode — Wrap any existing MCP server transparently
  • Zero config — Works standalone out of the box, config file for proxy mode

Quick Start

Standalone Mode

Add to your Claude Desktop / Claude Code config:

{

"mcpServers": { "selfheal": { "command": "npx", "args": ["-y", "selfheal-mcp"] } } }

Then use wrap_call to make any HTTP request with self-healing:

Use the wrap_call tool to GET https://api.example.com/data with target "example-api"
Proxy Mode

Create selfheal.config.json:

{

"mode": "proxy", "targets": [ { "name": "my-server", "transport": "streamable-http", "url": "https://my-mcp-server.com/mcp" } ] }

{

"mcpServers": { "selfheal": { "command": "npx", "args": ["-y", "selfheal-mcp"], "env": { "SELFHEAL_CONFIG": "/path/to/selfheal.config.json" } } } }

All tools from my-server are re-exposed with self-healing built in.

Tools

ToolDescription
wrap_callExecute HTTP call with retry + circuit breaker
circuit_statusCheck health of any target
circuit_resetReset circuit breaker after fixing issues
metricsSuccess rates, latency, top errors
recent_errorsRecent failures with full details
Proxy Mode Adds
ToolDescription
selfheal_metricsMetrics for all proxied calls
selfheal_circuitsCircuit status for all targets
selfheal_recent_errorsRecent errors across all targets

Configuration

Environment Variables
VariableDefaultDescription
SELFHEAL_CONFIG./selfheal.config.jsonConfig file path
SELFHEAL_MAX_RETRIES3Max retry attempts
SELFHEAL_BASE_DELAY_MS1000Base delay for backoff
SELFHEAL_MAX_DELAY_MS30000Max delay cap
SELFHEAL_CIRCUIT_THRESHOLD5Failures before circuit opens
SELFHEAL_CIRCUIT_COOLDOWN_MS120000Cooldown before half-open test

How It Works

Agent → SelfHeal MCP → [Retry + Circuit Breaker] → Target API/MCP Server

↓ Metrics Collector

  1. Request arrives — Agent calls a tool
  2. Circuit check — If target has failed too many times, reject immediately
  3. Execute with retry — Try the call, retry on transient errors with exponential backoff
  4. Record metrics — Log success/failure, duration, attempts
  5. Update circuit — Track consecutive failures per target
