Gemini CLIWorks today

Gemini CLI takes a remote MCP server over streamable HTTP with a static Authorization header.

You need a key first. API keys come with the Professional plan. Generate one on your account page, under API access. It starts with jbp_ and is shown once, so copy it when it appears. Everywhere below, replace jbp_your_key with it.

Set it up

Either the command or the config file. The command is faster.

With the command

gemini mcp add --transport http jbparcel https://jbparcel.com/mcp \
  --header "Authorization: Bearer jbp_your_key"

With the config file

Edit ~/.gemini/settings.json:

{
  "mcpServers": {
    "jbparcel": {
      "httpUrl": "https://jbparcel.com/mcp",
      "headers": {
        "Authorization": "Bearer jbp_your_key"
      }
    }
  }
}
Use httpUrl, not url. In Gemini CLI, url means an SSE endpoint. Our server is streamable HTTP and answers POST only, so an SSE-shaped config fails with a 405.

What you get

Once connected, three tools appear in your assistant:

ToolWhat it does
search_parcelsRuns the same advanced search the site runs. Filter by county, owner, acreage, year built, zoning, sale date, value, vacancy, absentee owners, LLC and trust owners.
get_parcelPulls one parcel's full record. Always free, never counted.
get_accountReports your plan and what is left of your budget.

Budgets are shared with the site and the REST API. Every row a search returns counts, at any page size: 20,000 rows per day. Parcel lookups have their own separate count, 1,600 per day, so pulling one property's full record never eats into search. CSV exports are kept apart from both and keep their own rolling 7-day and 30-day budgets.

If it does not connect

What you seeWhat it means
401 UnauthorizedThe key is missing, mistyped or revoked. Check the header reads exactly Authorization: Bearer jbp_... with one space after Bearer.
402, or a message about your planThe key is valid but the account is not on Professional. API and connector access come with Professional.
405 Method Not AllowedSomething sent a GET. Our server speaks POST only. This almost always means the client is configured for SSE instead of streamable HTTP.
Connects, but no tools appearRestart the client. Most read MCP config once at startup.
