Instructions

Implementation Reference

• src/mcp/tapp/pool-tools.ts:34-40 (handler)

  The handler function for the 'tapp_get_pool_info' MCP tool, which retrieves pool information via the TappAgent and returns formatted response.

  handler: async (agent: TappAgent, input: Record<string, any>) => {
      const poolInfo = await agent.getPoolInfo(input.poolId);
      return {
          status: "success",
          pool: poolInfo
      };
  },

• src/mcp/tapp/pool-tools.ts:31-33 (schema)

  Zod schema defining the input parameter 'poolId' for the tool.

  schema: {
      poolId: z.string().describe("The pool ID to get information for")
  },

• src/mcp/index.ts:28-28 (registration)

  Registration of the GetPoolInfoTool in the central TappExchangeMcpTools object.

  "GetPoolInfoTool": GetPoolInfoTool,

• src/index.ts:20-52 (registration)

  Dynamic MCP server.tool() registration loop that registers 'tapp_get_pool_info' using its name, description, schema, and wrapped handler.

  for (const [_key, tool] of Object.entries(TappExchangeMcpTools)) {
      server.tool(tool.name, tool.description, tool.schema, async (params: any): Promise<any> => {
          try {
              // Execute the handler with the params directly
              const result = await tool.handler(agent, params);
  
              // Format the result as MCP tool response
              return {
                  content: [
                      {
                          type: "text",
                          text: JSON.stringify(result, null, 2),
                      },
                  ],
              };
          } catch (error) {
              console.error("error", error);
              // Handle errors in MCP format
              return {
                  isError: true,
                  content: [
                      {
                          type: "text",
                          text:
                              error instanceof Error
                                  ? error.message
                                  : "Unknown error occurred",
                      },
                  ],
              };
          }
      })
  }

• src/agent/index.ts:230-233 (helper)

  TappAgent helper method called by the tool handler to fetch pool info from the SDK.

  async getPoolInfo(poolId: string): Promise<TappPool> {
      const info = await this.sdk.Pool.getInfo(poolId);
      return info;
  }
