Pilot Mcp Bridge Fleet Setup

Deploy an MCP and A2A bridge fleet with 3 agents. Use this skill when: 1. User wants to bridge MCP servers or A2A agents onto the Pilot network 2. User is configuring an MCP gateway, A2A bridge, or tool registry agent 3. User asks about connecting different agent ecosystems over Pilot tunnels Do NOT use this skill when: - User wants a single MCP bridge (use pilot-mcp-bridge instead) - User wants a single A2A connection (use pilot-a2a-bridge instead)

MCP Bridge Fleet Setup

Deploy 3 agents: MCP gateway, A2A bridge, and tool registry.

Roles

Role	Hostname	Skills	Purpose
mcp-gateway	<prefix>-mcp-gw	pilot-mcp-bridge, pilot-api-gateway, pilot-health, pilot-metrics	Bridges MCP tool servers
a2a-bridge	<prefix>-a2a-bridge	pilot-a2a-bridge, pilot-task-router, pilot-audit-log	Connects A2A protocol agents
tool-registry	<prefix>-tool-registry	pilot-directory, pilot-discover, pilot-announce-capabilities, pilot-load-balancer	Central tool directory

Setup Procedure

Step 1: Ask the user which role and prefix.

Step 2: Install skills:

# mcp-gateway:
clawhub install pilot-mcp-bridge pilot-api-gateway pilot-health pilot-metrics
# a2a-bridge:
clawhub install pilot-a2a-bridge pilot-task-router pilot-audit-log
# tool-registry:
clawhub install pilot-directory pilot-discover pilot-announce-capabilities pilot-load-balancer

Step 3: Set hostname and write manifest to ~/.pilot/setups/mcp-bridge-fleet.json.

Step 4: Both bridges handshake the registry.

Data Flows

• mcp-gateway → tool-registry : MCP tool registrations (port 1002)
• a2a-bridge → tool-registry : A2A agent registrations (port 1002)
• tool-registry → mcp-gateway : tool call routing (port 1002)
• tool-registry → a2a-bridge : task routing (port 1002)

Workflow Example

# On mcp-gateway — register a tool:
pilotctl --json publish <prefix>-tool-registry tool-register '{"name":"web-search","protocol":"mcp"}'
# On tool-registry — route a call:
pilotctl --json publish <prefix>-mcp-gw tool-call '{"call_id":"C-401","tool":"web-search","params":{"query":"Pilot Protocol"}}'
# On mcp-gateway — return result:
pilotctl --json publish <prefix>-tool-registry tool-result '{"call_id":"C-401","result":{"url":"https://pilotprotocol.network"}}'

Dependencies

Requires pilot-protocol skill, pilotctl binary, clawhub binary, and a running daemon.
