Use the Pomerado MCP in a chat client as a personal assistant for tasks on websites. This guide uses Instacart.

​
Connect

In a chat client that supports custom MCP connectors, add https://mcp.pomerado.ai/mcp and sign in. To try it without an account, add https://mcp.pomerado.ai/mcp/keyless instead. See client setup.

​
Compare prices across stores

Ask a question that needs a lot of data at once:
Compare the prices of eggs, oat milk, bananas and coffee at the Instacart stores near 94103, and tell me where my list costs least.
The agent finds an Instacart search tool with find_website_tool, then calls run_read_only_website_tool once for each item, all at the same time:
Read-only runs change nothing on the site, so they can run in parallel. Each usually returns in seconds, and the agent combines the results into one answer. A search that needs no Instacart login also works on the keyless connection, within its daily limit.

​
Build a missing tool

When no tool covers a task, ask the agent to build one:
Build a tool that lists my past Instacart orders.
The agent calls build_website_tool, tells you it’s building, and follows the job. A build takes about 10 minutes and needs you to be signed in to Pomerado. If it needs your Instacart login, the agent gives you a link to a protected page: enter the login there, never in chat.

​
Track the build

  • In chat: the agent calls get_job with wait_seconds. Each call returns when the job asks a question or finishes, or when the wait ends; the agent calls again while it runs.
  • On the Dashboard: open the job’s watch_url.
  • Elsewhere: create a webhook on the Dashboard under Settings, then Webhooks, to be told when a job asks a question (job.needs_input) or finishes (job.succeeded, job.failed).
When the job succeeds, its tool_id names the new tool, and the agent can run it right away.
  • How long one call can wait depends on the client. See wait for a result.
  • Clients that support MCP events get the same job events without a webhook. See MCP events.
  • Set up a webhook in webhooks.
