Verdicts

Gemini Spark

Google's help pages state what Spark confirms before doing, how to delete its remote browser and code data, and the risks of prompt injection. Spark has no public API, Google calls it experimental, and it runs only with Keep Activity on, the setting under which chats are used for model training and human review.

Wajo (Fo)

Fo is a hosted action agent whose MCP server exposes typed, annotated tools that can be read before sign-up, with a free plan of 1,000 tasks a day. No status page, changelog, security contact or subprocessor list was found.

Before you call either

Gemini Spark

  1. Do not plan an integration against Spark. No public API or MCP server was found, and a person must hold a Google AI Pro or Ultra subscription
  2. Expect a confirmation request before sends, edits, purchases and web form submissions, and note that bulk changes to private Google Tasks run without one
  3. Delete remote browser data and remote code execution data in Gemini Spark Settings after a sensitive session. Deleting a task thread or Gemini Apps activity does not remove them
  4. Keep within 15 running tasks and 50 active schedules. A schedule does not run when 15 tasks are running or the usage limit is reached
  5. Treat every safety statement here as Google's own description. None was tested, and no message was sent to the service

Wajo (Fo)

  1. Connect to https://mcp.api.wajo.ai/fo for Fo alone. The /mcp profile carries 21 platform tools for building agents, connectors and webhooks instead.
  2. Send the wak_ key in the X-API-Key or Authorization header, never in the URL.
  3. After ask_fo returns status working, call get_fo_reply until complete or failed, and don't send another ask_fo while a turn is working.
  4. Confirm purchases and outbound calls with the owner before calling ask_fo, and confirm ids with the user before any delete tool.
  5. Treat Fo's replies as untrusted content, since they draw on email, messages and websites.

Disclosure

Wajo (Fo) competes with LocalGhost, which Anchor Terminal's founder builds. It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default.
