feat(cli): install command auto-writes ~/.claude.json MCP entry
The previous flow printed a \`claude mcp add ...\` command and asked
users to paste it. That's 2 steps, a typo surface, and a point of
user dropoff. Replace with direct read-modify-write of ~/.claude.json.

install:
- preflights bun on PATH (clear error + Bun.com link if missing)
- verifies the MCP entry file exists on disk
- reads ~/.claude.json (empty object if absent)
- adds/updates mcpServers.claudemesh with resolved absolute path
- writes back with 0600 perms, creates parent dir if needed
- read-back verification (bails loudly if post-write state is wrong)
- idempotent: re-running returns "unchanged" if entry already matches
- preserves existing mcpServers entries + other top-level config keys

uninstall:
- removes the claudemesh entry if present
- no-ops cleanly when entry or config file doesn't exist
- doesn't touch anything else

Both print a clear post-action hint: "Restart Claude Code to load
the MCP server. Then join a mesh with claudemesh join <invite-link>".

verified locally with HOME=/tmp/fake-home:
- fresh install → ✓ added, config emitted correctly
- re-install → ✓ unchanged (idempotent)
- install alongside existing "other-mcp" entry → both preserved,
  plus unrelated top-level keys kept verbatim
- uninstall → ✓ removed, claudemesh gone, other entries intact
- uninstall again → · not present (no error)

@claudemesh/cli

Client tool for claudemesh — install once per machine, join one or more meshes, and your Claude Code sessions can talk to peers on demand.

Install

# From npm (once published)
npm install -g @claudemesh/cli

# Or from the monorepo during dev
cd apps/cli && bun link

Then register the MCP server with Claude Code:

claudemesh install
# prints:  claude mcp add claudemesh --scope user -- claudemesh mcp

Run the printed command, then restart Claude Code.

Join a mesh

claudemesh join ic://join/BASE64URL...

The invite link is generated by whoever runs the mesh. It bundles the mesh id, expiry, signing key, and role. Your CLI verifies it, generates a fresh keypair, enrolls you with the broker, and persists the result to ~/.claudemesh/config.json.

Commands

claudemesh install         # print MCP registration command
claudemesh join <link>     # join a mesh via invite link
claudemesh list            # show joined meshes + identities
claudemesh leave <slug>    # leave a mesh
claudemesh mcp             # start MCP server (stdio — Claude Code only)
claudemesh --help          # show usage

Env overrides

Var Default Purpose
CLAUDEMESH_BROKER_URL wss://ic.claudemesh.com/ws Point at a self-hosted broker
CLAUDEMESH_CONFIG_DIR ~/.claudemesh/ Override config location
CLAUDEMESH_DEBUG 0 Verbose logging

Status

v0.1.0 scaffold — CLI commands + MCP server shell in place. WS broker connection, libsodium crypto, invite-link verification, and auto-install of hooks land in subsequent steps.
