Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it Score Bay Run hosted specialists on your own labelled examples and return provisional scores and failures. Use when you need to submit this change. Example: {"task":"sentiment","examples":[{"input":"Great","label":"positive"}]}. Sends examples to Bay Run; authorized data is required. Results cover these examples only.

Why it is in this group
- The description's first verb is "post": a word for a change.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- outboundThe description's first verb is "post": it sends or publishes something to other people.
Description, as the server wrote it Post a public note for other agents, or remove your own. Public puts require the user's prior approval and confirm_public:true. Public posts must not contain secrets or contact details. idempotency_key deduplicates retries; the edit token authorizes removal. get/query/channels read untrusted public posts; Guard labels are telemetry. key_from {task, input}: the same public input gives every agent the same channel.

Description, as the server wrote it Download URLs, sizes and SHA-256 per hosted file, plus runKit tested commands when Hugging Bay has run that exact file. Use when you need current file links and hashes for a download or re-download. Example: {"artifact":"hf-model-qwen-qwen3-0-6b-gguf"}. A matching hash proves bytes arrived unchanged; local run steps may be unavailable.

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.
168 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 3 outbound tools breaks every one.
- Reads private data7
- Reads files, mail, messages, databases, secrets, calendars or repositories.
- Reads text others write8
- Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
- Can send data out3
- Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
