+# packages/mcp-server
+
+## Scope
+
+- This package is the MCP/JSON-RPC adapter over the API server.
+- `src/protocol/tools.ts` defines tool schemas.
+- `src/protocol/handler.ts` maps tool calls to API requests and JSON-RPC responses.
+- `src/protocol/metadata.ts` exposes discovery metadata and protocol versioning.
+
+## Keep In Sync
+
+- Tool definitions, handler argument mapping, and server metadata must stay consistent.
+- When adding or renaming a tool, update `tools.ts` and `handler.ts` together.
+- If protocol version or server-card details change, update both `metadata.ts` and initialize responses in `handler.ts`.
+
+## Protocol Rules
+
+- Use MCP/JSON-RPC error codes and response envelopes, not ad-hoc API-style payloads.
+- Keep this layer transport-focused. Marketplace behavior belongs in `packages/core`; HTTP semantics belong in `packages/api-server`.
+- Preserve the current tool result shape unless the protocol contract is being changed deliberately: text content with JSON-stringified API results.
+
+## Verify
+
+- `bun run --cwd packages/mcp-server build`
+- `bun run ci`
