Marketo MCP Server

Implementation Reference

• src/index.ts:497-517 (registration)

  Registration of the 'marketo_delete_lead' MCP tool, including inline input schema (leadId: z.number()) and handler function that performs a POST request to the Marketo API endpoint `/rest/v1/leads/${leadId}/delete.json` using the shared makeApiRequest helper.
  server.tool( 'marketo_delete_lead', { leadId: z.number(), }, async ({ leadId }) => { try { const response = await makeApiRequest(`/rest/v1/leads/${leadId}/delete.json`, 'POST'); return { content: [{ type: 'text', text: JSON.stringify(response, null, 2) }], }; } catch (error: any) { return { content: [ { type: 'text', text: `Error: ${error.response?.data?.message || error.message}` }, ], }; } } );
• src/index.ts:502-516 (handler)

  The core handler logic for executing the marketo_delete_lead tool: authenticates via token, sends POST to delete endpoint, returns JSON response or error message.
  async ({ leadId }) => { try { const response = await makeApiRequest(`/rest/v1/leads/${leadId}/delete.json`, 'POST'); return { content: [{ type: 'text', text: JSON.stringify(response, null, 2) }], }; } catch (error: any) { return { content: [ { type: 'text', text: `Error: ${error.response?.data?.message || error.message}` }, ], }; } }
• src/index.ts:499-501 (schema)

  Zod input schema defining the required 'leadId' parameter as a number.
  { leadId: z.number(), },
• src/index.ts:22-52 (helper)

  Shared helper function makeApiRequest used by all Marketo tools, including marketo_delete_lead, to handle authenticated API calls with axios, token management, and error handling.
  async function makeApiRequest( endpoint: string, method: string, data?: any, contentType: string = 'application/json' ) { const token = await tokenManager.getToken(); const headers: any = { Authorization: `Bearer ${token}`, }; if (contentType) { headers['Content-Type'] = contentType; } try { const response = await axios({ url: `${MARKETO_BASE_URL}${endpoint}`, method: method, data: contentType === 'application/x-www-form-urlencoded' ? new URLSearchParams(data).toString() : data, headers, }); return response.data; } catch (error: any) { console.error('API request failed:', error.response?.data || error.message); throw error; } }
