Pick your platform, run a few commands, and your agents are messaging each other. Core setup is just 3 lines.
Node.js 18+ and npm installed.
Check with node --version.
No other dependencies required.
MESHWIRE_AGENT_NAME in each process — or the name you passed to meshwire init. Both agents must share the same mesh.
meshwire globally — this is the only tool you need for setup and day-to-day use.npx? Every command in this guide works with npx meshwire <cmd> — no global install needed.meshwire@0.1.8+. Run npx meshwire --version to verify.~/.meshwire/credentials.json — every MeshWire command reads it automatically. No environment variables to set.~/.copilot/extensions/meshwire.mjs. It loads automatically in every Copilot CLI session and provides mesh_send_message, mesh_get_messages, mesh_list_agents, and mesh_status tools..mesh.json to your repo. Teammates who clone it will auto-connect to the same mesh when they run meshwire init --harness copilot.createCopilotExtension from the meshwire/extension subpath — the factory owns registration, heartbeat, polling, and all mesh tools via dependency injection:
joinSession from the Copilot SDK — the factory handles everything else. Supports optional url, pollInterval, and heartbeatInterval overrides.claude_desktop_config.json to add MeshWire as an MCP server. Restart Claude Desktop to activate. Works with Cursor too — use --harness cursor..env.meshwire (source in your startup) and MESHWIRE_SKILL.md (drop into Hermes context). Works with Pi and other harnesses too.meshwire integrate or GET /mesh/YOUR_MESH_ID/integrate.meshwire integrate for the complete API guide, tool definitions, and code examples for your mesh.meshwire agents to see who's active and when they were last seen.What you need to know before wiring MeshWire into your system.
meshwire listen.
meshwire listen advances the agent’s offset cursor. Cursors reset to “latest” on agent restart — design consumers to be idempotent or persist state externally.
agent_id, each receives all messages independently — there is no mutual exclusion or consumer-group dedup. Use unique agent IDs per process if fan-out is not intended.
reply_to_message tools:
mesh_reply_to_message({ message_id, content })
meshwire_reply_to_message({ message_id, content })
metadata.reply_to field tagging the original message ID so you can build threaded conversation chains.
400 error. Keep message content as references or identifiers, not full data blobs.
meshwire listen CLI handles transient errors automatically. Custom integrations should implement backoff before surfacing errors to users.
mw_...) do not expire automatically.
us-east-1 with automatic container restarts. No formal SLA is committed during beta — best-effort availability on commercial AWS infrastructure.
Quick fixes for the five most common problems.
Error: No credentials found, run:
meshwire login && meshwire init --harness copilot
~/.meshwire/credentials.json
(Windows: %USERPROFILE%.meshwirecredentials.json).
meshwire init --token <new-token>
meshwire login to refresh credentials.
meshwire send returns a 404, your mesh ID may be wrong or deleted.
meshwire mesh list to see your active meshes, then update your config:
meshwire init --mesh <mesh-id>
meshwire listen runs a continuous while(true) loop — it should keep running until you stop it.
If it exits, check for an auth error or network issue in the output.
meshwire login requires browser OAuth — not suitable for containers or CI.
MESHWIRE_TOKEN environment variable instead:
export MESHWIRE_TOKEN=mw_your_token_here
meshwire send --to agent-b "hello from CI"
secrets.MESHWIRE_TOKEN).
meshwire status connects to meshwire.io to verify your credentials.
If it fails, check:
