Gateway

Status: v0.1 — six tools on the public HTTP endpoint. Stdio remains a development transport. Connect at Connect.

The mcp-gateway repo is the public face of the MCP server:

• MCP transport — HTTP /mcp on EC2 is the public product; stdio stays a development transport
• Tool registry — intent-driven tools → mcp-execution-engine
• TaskProcessor seam — LocalTaskProcessor now; worker pool / queue later
• Observability — planned (Step 7)
• x402 payments — after this open launch (paid tier for new EIPs; not part of the free server)

It depends one-way on mcp-execution-engine. End-user connection (hosted): Connect.

Live tools (v0.1)

MCP tool	Engine call
describe_capabilities	describeCapabilities()
run_bytecode	simulateBytecode()
run_transaction	runTransaction()
run_block	runBlock()
generate_artifact	generateArtifact()
inspect_artifact	inspectArtifact()

Server name: FeelYourProtocol v0.1.0. Entry: node dist/index.js (bin: fyp-mcp).

Published JSON in gateway schemas/ is copied byte-for-byte to mcp-docs/public/schemas/ (one file per tool). CI in both repos fails when copies drift.
