Akm Bridge

Controlled, read-only adapter for AKM v0.8.1 in OpenCode v1.16.0.

Components

Component	Path	Purpose
Adapter library	src/adapter.ts	Core AKM binary wrapper with exit code 4 hardening
MCP server	src/mcp-server.ts	JSON-RPC over stdio — 14 AKM tools for OpenCode
HTTP API	src/http-server.ts	REST API on 127.0.0.1:4199
Types	src/types.ts	Normalized response contracts
Config	src/config.ts	Binary path, timeouts, limits

Quick Start

cd /root/projekt/akm-bridge
bun install
bun run build
bun test
bun run start          # MCP server (stdio)
bun run start:http     # HTTP API
bun run dev:mcp        # MCP from source (tsx)

Architecture

OpenCode
├── CLI shell ──────→ akm
├── MCP ───────────→ akm-bridge ──→ akm CLI
└── AGENTS.md ─────→ supervised workflow instructions

Plugin decision: akm-opencode is intentionally not installed. The production integration is CLI + MCP bridge + AGENTS.md. See docs/AKM-OPENCODE-INTEGRATION.md for full rationale.

Exit Code 4 Note

akm health exits with code 4 (warn status). The adapter accepts this only when stdout is valid JSON containing a health/warn response. All other non-zero exit codes are rejected. See docs/AKM-OPENCODE-INTEGRATION.md.
