Distillation

🟡 (19:53) mcpHandlers in packages/opencode/src/server/routes/instance/httpapi/handlers/mcp.ts:8-110 acquires MCP.Service once while constructing the handler layer at line 10, adding another target-route service resolved during instance-scoped layer initialization.
🟡 (19:53) GET /mcp is implemented by McpHttpApi.status at packages/opencode/src/server/routes/instance/httpapi/handlers/mcp.ts:12-14; it directly returns mcp.status() and is registered via .handle("status", status) at line 102.
🟡 (19:53) MCP handler operations exposed from the same captured MCP.Service are: add using mcp.add() at lines 16-21; authStart using mcp.supportsOAuth() and mcp.startAuth() at lines 23-34; authCallback using mcp.finishAuth() at lines 36-49; authAuthenticate using mcp.supportsOAuth() and mcp.authenticate() at lines 51-62; authRemove using mcp.status() and mcp.removeAuth() at lines 64-73; connect using mcp.connect() at lines 75-86; and disconnect using mcp.disconnect() at lines 88-99.
🟡 (19:53) The MCP handler explicitly maps MCP.NotFoundError to McpServerNotFoundError for OAuth, connect, and disconnect operations, and maps status-schema decoding failure to HttpApiError.BadRequest; it contains no explicit abort handling or HTTP 499 mapping.
