Cassandra prediction hub: one MCP door over govcon forecasts (recompete, contractor signals).The vendor's description, from its MCP Registry listing.
- Warning: The server only speaks the first MCP version (2024-11-05).
- Warning: 2 of 2 tools do not say whether they can change things.
Nothing failed, but there is something to know or fix. Public audit: we connect as an AI client would, list the tools and check what they say. We do not run them. How we audit
- Does it work?
- YesConnected in 145 ms.
- Sign-up?
- None neededIt answered without any account or key.
- Can it change things?
- Doesn't sayIts tools do not say whether they only read, so treat them as able to change things.

What we checked
Security
Passed: Connections are encrypted (HTTPS).
Passed: No hidden instructions found in tool text.
Safety labels
Warning: 2 of 2 tools do not say whether they can change things.
MCP lets a server label each tool as read-only or destructive, so clients can ask the user before risky calls. Unlabelled tools are treated as able to change things.
- predict
- list_domains
Tools
Passed: 2 tools listed.
Passed: Every tool describes its inputs with a valid schema.
Protocol
Warning: The server only speaks the first MCP version (2024-11-05).
Newer versions (latest 2025-11-25) add tool safety labels, structured output and a safer authorization model.
Passed: The MCP handshake works (Streamable HTTP).
Passed: Unknown requests are refused.
Connection
Passed: The server responds.
Tools (2)
As the server describes them. The labels are the server's own: it says whether each tool only reads or can change things.
