Antigravity

Antigravity caps MCP servers at 100 tools total across all configured servers. EMCP Tools registers well over 100 tools when Elementor Pro is active, over the cap. Flip on Compact tool mode before connecting or Antigravity will refuse to load the server with no error message.

Step 1: Enable Compact tool mode (critical)

1. In WordPress admin, go to EMCP Tools → Tools.
2. At the top of the page, toggle on Compact tool mode.
3. Click Save Changes.

This collapses the whole surface to just 3 dispatcher meta-tools (list-tools, get-tool-schema, and call-tool), well under the 100-tool cap. Every other tool stays reachable through call-tool: the agent discovers a tool with list-tools, fetches its inputs with get-tool-schema, then runs it with call-tool. Your per-tool enable/disable toggles on the Tools tab still apply. call-tool refuses anything you’ve disabled. See Compact tool mode for the full flow.

Step 2: Configure Antigravity

Connect with OAuth (sign in through the browser, recommended) or an Application Password.

Option A, OAuth via mcp-remote (recommended)

Antigravity connects over stdio, so OAuth runs through the mcp-remote bridge, which handles the browser sign-in and token refresh:

{
  "mcpServers": {
    "emcp-tools": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://your-site.test/wp-json/mcp/emcp-tools-server"]
    }
  }
}

The first run opens your browser to approve access from your WordPress login. Requires Node 18+ and an HTTPS site with OAuth enabled (EMCP Tools → Connection: on by default on HTTPS). Revoke access any time under Connected apps.

Option B, Application Password

{
  "mcpServers": {
    "emcp-tools": {
      "url": "https://your-site.test/wp-json/mcp/emcp-tools-server",
      "headers": {
        "Authorization": "Basic BASE64_ENCODED_CREDENTIALS"
      }
    }
  }
}

Generate the base64 credentials:

echo -n "admin:xxxx xxxx xxxx xxxx xxxx xxxx" | base64

(Application passwords come from WordPress admin → Users → Profile → Application Passwords.)

Step 3: Verify

Open Antigravity and ask it to list MCP tools. You should see exactly 3 emcp-tools-* tools (list-tools, get-tool-schema, call-tool). That’s expected in Compact tool mode; the agent reaches everything else through call-tool. If you see zero, the server hit the cap. Double-check Compact tool mode is on in WordPress admin, then restart Antigravity.

Why this happens

Antigravity treats the 100-tool ceiling as a hard limit and silently drops servers that exceed it. There’s no error in the UI. The server just won’t appear. Compact tool mode sidesteps the cap entirely by exposing only 3 dispatcher tools regardless of how many tools you have enabled.

If you need to restrict which tools the agent can run through call-tool, disable them on EMCP Tools → Tools. call-tool refuses any disabled or unknown tool (and enforces each tool’s own capability check), so your toggles remain the source of truth even in Compact tool mode.
