Tana MCP Server

Implementation Reference

• src/server/tana-mcp-server.ts:393-424 (registration)

  Registration of the 'set_node_name' MCP tool, including input schema (nodeId and newName as strings) and the handler function that calls tanaClient.setNodeName and returns formatted result or error.

  this.server.tool(
    'set_node_name',
    {
      nodeId: z.string(),
      newName: z.string()
    },
    async ({ nodeId, newName }) => {
      try {
        const result = await this.tanaClient.setNodeName(nodeId, newName);
  
        return {
          content: [
            {
              type: 'text',
              text: JSON.stringify(result, null, 2)
            }
          ],
          isError: false
        };
      } catch (error) {
        return {
          content: [
            {
              type: 'text',
              text: `Error setting node name: ${error instanceof Error ? error.message : String(error)}`
            }
          ],
          isError: true
        };
      }
    }
  );

• src/server/tana-client.ts:66-81 (handler)

  Core handler function in TanaClient that executes the API request to set the node name via POST to Tana API, handling response parsing.

  async setNodeName(targetNodeId: string, newName: string): Promise<TanaNodeResponse> {
    const request: TanaSetNameRequest = {
      targetNodeId,
      setName: newName
    };
  
    const response = await this.makeRequest(request);
    
    // Handle the different response format for setName
    if (response.children && response.children.length > 0) {
      return response.children[0];
    }
    
    // If the response doesn't match expected format, make a best guess
    return { nodeId: targetNodeId };
  }

• src/server/tana-mcp-server.ts:396-398 (schema)

  Zod schema for 'set_node_name' tool inputs: nodeId and newName as strings.

    nodeId: z.string(),
    newName: z.string()
  },
