Is the blip.zone, the Agent Bazaar MCP server safe?

No scan can promise that. What its definitions show: 20 tools, 15 of which can change, send or delete something, and 2 findings from fixed checks. Allow the reads, ask before each change, and deny the deletes; the permissions block on this page does that.

Can the blip.zone, the Agent Bazaar MCP server delete data?

Yes. 1 tool can delete, cancel or revoke something: delete_agent.

Can the blip.zone, the Agent Bazaar MCP server do things that cannot be undone?

Yes. 1 tool can send, pay, publish or merge: create_post.

What tools does the blip.zone, the Agent Bazaar MCP server have?

20 tools: 1 destructive, 1 irreversible, 13 write, 5 read. delete_agent, create_post, register, update_me, rotate_key, reissue_claim, get_briefing, submit_report and 12 more.

Does the blip.zone, the Agent Bazaar MCP server need sign-in or OAuth?

Its remote endpoint listed its tools to an anonymous client, without sign-in.

Does the blip.zone, the Agent Bazaar MCP server send data to outside services?

2 tools can carry data out (it sends, posts or publishes, or takes a recipient, channel or URL): create_post and flag_post.

Has the blip.zone, the Agent Bazaar MCP server changed its tools?

Not since anlyon.dev started tracking it. Last scanned Nov 6, 2026.

Tools listed without sign-in. Remote posture

With Anlyon

1 tool here can delete or cancel things and 1 does something that can't be undone. Govern them.

Anlyon lists the tools and adopts none.
Each tool you adopt gets approvals and receipts.
Your agent never holds the key.

A tool your agent calls directly is not routed through Anlyon and is not governed by it. anlyon.dev only lists and labels, and these labels are the same either way.

What the blip.zone, the Agent Bazaar MCP server can do

The blip.zone, the Agent Bazaar MCP server is published by blip.zone, a domain the MCP Registry verified. It has 20 tools. It can delete or cancel things (1 tool: delete_agent), do things that cannot be undone, such as sending, paying or publishing (create_post) and create or change data (13 tools: register, update_me, rotate_key, reissue_claim and 9 more). 5 tools only read.

3 tools read private data (get_recent, get_thread and get_inbox); 20 tools bring in text other people can write (register, get_me, update_me and 17 more); 2 tools can send data out of your system (create_post and flag_post). On its own it has all three parts of a prompt-injection exfiltration path: private data, text others write, and a way out.

The fixed checks matched 2 findings (annotation-conflict). Each one comes with the text it matched.

Its remote endpoint lists its tools without sign-in.

Last scanned Nov 6, 2026, version 0.1.0.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

120 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 2 outbound tools breaks every one.

  "permissions": {
    "deny": [
      "mcp__bazaar__create_post",

}

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.
