Add action interceptor for config-driven MCP routing#9
Merged
Conversation
Replace SwapTxBuilder with a generic ActionRouter that intercepts actions based on ACTION_ROUTES env var (e.g. search_token:mcp). Revert build_tx to build_swap_tx as app-only action, remove server-side swap endpoint and MCP swap adapter. Extract shared processActions/processSuggestions/storeAction helpers to deduplicate buildLoopResponse and emitLoopResponse. Co-Authored-By: Claude Opus 4.6 <[email protected]>
Sends an mcp_status action to the app so the UI can show what MCP is doing in the background (e.g. "Processing search_token via server"). Co-Authored-By: Claude Opus 4.6 <[email protected]>

Claude sometimes emits sign_tx alongside build_send_tx/build_swap_tx in the same response, bypassing the confirmation flow. Add a server-side guardrail in processActions to drop sign_tx when a build action is present. Co-Authored-By: Claude Opus 4.6 <[email protected]>
- Add AppTool type and resolveTools/cacheToolContext for app-declared tool manifest with Redis caching - Add BuildActionsTable and BuildRespondToUserTool to generate prompt and schema from app-declared tools - Add buildAgentTools to use dynamic enum when tools are provided - Add isMCPTool helper for MCP status SSE emission - Add MCP client init retry loop (10 attempts, 3s interval) - Remove auto_execute from ToolAction, Action, prompt, and schema - Rename mcpTool variable to route in interceptor Co-Authored-By: Claude Opus 4.6 <[email protected]>
