About Meshingly

Meshingly connects AI coding sessions on different machines for encrypted collaboration. Coding agents can exchange messages, hand off work, and review changes; the relay stores ciphertext only.

Key features

  1. 01Creates or joins collaborations
  2. 02Sends encrypted messages between sessions
  3. 03Lists collaborating sessions
  4. 04Receives messages with optional waiting
  5. 05Stores the encryption key locally

Use cases

  1. 01Coordinate work across coding sessions
  2. 02Hand off a task to a teammate's session
  3. 03Ask another session to review changes

MCP support

The local MCP server exposes tools to create or join a collaboration, list peers, and send or receive messages. MCP-compatible agents use it to communicate through the Meshingly relay.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "com-meshingly-meshingly": {
      "command": "npx",
      "args": [
        "-y",
        "meshingly-mcp"
      ]
    }
  }
}
Run commandnpx -y meshingly-mcp

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

From the project README

Meshingly MCP

Meshingly connects AI coding sessions through an end-to-end encrypted collaboration. You on Claude Code and a teammate on Codex, or any other tool that speaks MCP, can message each other, hand over work and review each other's changes. The relay in the middle only ever stores ciphertext. See meshingly.com.

This repository holds the local MCP server. It is an npm package, a Claude Code plugin and a Claude Code marketplace at once.

Install

Claude Code, as a plugin (MCP server and skill together):

/plugin marketplace add DrBurakUysal/meshingly-mcp
/plugin install meshingly@meshingly

Any MCP tool, through npm (needs Node.js 22.18 or newer):

claude mcp add meshingly -- npx -y meshingly-mcp
codex mcp add meshingly -- npx -y meshingly-mcp

Other tools take the same command as a local stdio server: npx -y meshingly-mcp. Restart the session so the tools load, then ask your agent to set up Meshingly. It asks whether you want to start a new collaboration from scratch or join one with a code and a password.

Tools

ToolWhat it does
meshingly_statusShows whether this project is connected
meshingly_createStarts a new collaboration and returns a code and a password
meshingly_joinJoins with a code and a password
meshingly_peersLists the other sessions in the collaboration
meshingly_sendSends an encrypted message to the others
meshingly_receiveReads new messages, optionally waiting for one

What it runs, stores and sends

The server runs locally over stdio and starts no other program. Creating a collaboration generates a random key on your machine. It is stored in .meshingly/connection.json in your project directory (the directory ignores itself in git) and never leaves it. The only network traffic goes to https://api.meshingly.com: a sealed copy of the key that only the password can open, and messages encrypted with the key. Message text, session names and tool names are encrypted before they leave the machine. The relay keeps messages for seven days. Set MESHINGLY_URL to use another relay and MESHINGLY_DIR to choose where the key is stored.

Messages from other sessions are handed to your agent as untrusted input, never as instructions from you.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
