Works with Claude, with some setup first

Install Node.js on your computer first (one time) · Only the Claude desktop app (Windows or Mac), not the web or phone

Let AI install it

Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server SelfHeal MCP for Claude on this computer, in this order: 1) Check Node.js with node -v. If it is missing, tell me to install it from https://nodejs.org/en/download; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "selfheal": { "command": "npx", "args": [ "-y", "selfheal-mcp" ] } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) No key is needed. 5) Do what we agreed, then check that the SelfHeal MCP tools really show up.

This message has no key in it. If a key is needed, the AI will ask you to paste it yourself into the file or the app’s field.

  1. Install Node.js (if you don’t have it)

    Already installed? Check first · Open Terminal, type this command and press Enter

    node -v
    • A version number such as v26.13.1 = installed, skip this step
    • "command not found" (on Windows: "is not recognized") = not installed yet, or installed but Terminal needs to be closed and reopened
    How to open Terminal

    Mac: press ⌘ + Space, type Terminal, press Enter

    Windows: open Start, type Windows PowerShell, then Open

    Not installed: Open the official download page, pick the LTS version and the click-through installer: .pkg on Mac · .msi on Windows. Double-click and follow it to the end. No curl command needed

    Open the Node.js download page ↗

    When it’s done, close Terminal, open it again and run the same command. You should see a version number: node -v

    Install once; it works for everything that needs Node.js

  2. Open the Claude desktop app’s settings file

          ]
        }
      }
    }
  4. Quit Claude and open it again

  5. Try it

    Use SelfHeal MCP and tell me what you can do for me, then show me one thing

    ✓ If Claude says it is using SelfHeal MCP or shows a SelfHeal MCP tool in the answer, you are connected

3 optional setting(s) (works without them)

The command above works without these. Add them only if you want to change something, following the maker’s description.

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

Common questions

Is SelfHeal MCP safe?

It passed 2 of 3 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 4 months ago, 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
