Verify email addresses from Cursor with MCP

1. 1
   In PricklyMails

   Create an agent in PricklyMails

   1. In the dashboard, open Agents and click New agent.
   2. Give it a name, such as Cursor, and tick under Scopes what it may do: verify one address, verify a list, read results, check your balance.
   3. Click Create agent.

   Note

   The Free plan creates one agent, which verifies one address at a time and reads results; every paid plan can grant an agent any scope.

   Add the PricklyMails server to Cursor

   Cursor reads its MCP servers from mcp.json: ~/.cursor/mcp.json for every project, .cursor/mcp.json for one. The button below the steps adds the same server for you.

   1. Open ~/.cursor/mcp.json, or .cursor/mcp.json at the root of a project, and create it if it does not exist.
   2. Add the pricklymails server below under mcpServers, then save the file.
   3. Restart Cursor.
   4. Open Customize in the sidebar, then MCPs, and check that PricklyMails is turned on.

   ~/.cursor/mcp.json

   {
       "mcpServers": {
           "pricklymails": {
               "url": "https://mcp.pricklymails.com/mcp"
           }
       }
   }

   Approve the agent in PricklyMails

   1. When Cursor opens PricklyMails in your browser, sign in to your account.
   2. Under Choose which agent to authorize, pick the agent you created.
   3. Click Authorize.

   Tip

   No key is pasted anywhere: the agent is what grants access, and revoking it from Agents cuts it off at once.

   Ask Cursor's agent to verify addresses

   1. In the agent's chat, ask for a verification in plain words.
   2. When Cursor asks to run a PricklyMails tool, click the arrow next to the tool's name to see its arguments, then approve it.

   Then ask in plain words, for instance:

   • Verify jane.doe@acme.com before I reply to her.
   • Here are the 40 addresses from my event signup sheet: verify them and tell me which ones to remove.
   • How many PricklyMails tokens do I have left this month?

   Tip

   To skip the approval for a tool that only reads, such as get_pricing, add pricklymails:get_pricing to mcpAllowlist in ~/.cursor/permissions.json.

What it can do

Within the scopes of its agent, Cursor can verify one address or a whole list, read the results and their reasons, check your balance and usage, and manage your API keys and webhooks. Each call is billed like the same request through the API.
