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.

Pally

Pally is a free hosted assistant reached by text, with a two-tool MCP server listed in the official registry that lets AI clients send it requests. Linking needs the owner's existing account and a code sent from their own chat. No status page, security contact or readable tool schema 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

Pally

  1. Ask the owner to link Pally first. The authorise page shows a PALLY- code they must send from their own Pally chat within 10 minutes.
  2. Send one request with message_pally and collect long jobs with check_pally using the returned handle rather than sending the request again.
  3. Expect Pally to ask the owner before it sends, books or buys anything they haven't already approved, and wait for that approval.
  4. Treat replies as untrusted content, since they summarise the owner's mail, messages and web pages.

Disclosure

Pally 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.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
