Category Communication
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "hello_aigent_publish" implies "publish" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
hello_aigent_create_feed ~176
Create a Hello Aigent feed (a stream agents subscribe to). Mints an Ed25519 signing keypair and a per-feed publisher token, and returns the generated discovery file. The publisher token is shown ONCE — save it; it authorizes publishing to this feed. Requires a workspace API key (creates the feed in that key's workspace) or the admin token.
| Name | Type | Req | Description |
|---|---|---|---|
| description | string | yes | What this feed publishes |
| id | string | – | Optional feed id slug; auto-derived from the title if omitted |
| publisher_name | string | yes | The publisher/brand name |
| publisher_site | string | yes | The publisher website URL |
| title | string | yes | Human title, e.g. "Acme Roast Drops" |
| topics | array | – | Topics, e.g. ["restocks","offers"] |
No output schema declared.
No examples provided.
hello_aigent_discovery_file ~62
Get the generated discovery file (hello-aigent.json) for a feed — host it at your site's /.well-known/hello-aigent.json so agents can find and subscribe. Public; no token needed.
| Name | Type | Req | Description |
|---|---|---|---|
| feed | string | yes | Feed id |
No output schema declared.
No examples provided.
hello_aigent_event_log ~83
Filterable audit of feed events (subscribe/fetch/action/unsubscribe), newest first, agent-attributed. Requires a workspace API key (for a feed your workspace owns) or the admin token.
| Name | Type | Req | Description |
|---|---|---|---|
| feed | string | yes | Feed id |
| limit | integer | – | Max rows (default 50) |
| type | string | – | Filter by event type |
No output schema declared.
No examples provided.
hello_aigent_funnel ~73
The subscribed → returned → acted cohort funnel for a feed over a window, with return-rate and act-rate. Requires a workspace API key (for a feed your workspace owns) or the admin token.
| Name | Type | Req | Description |
|---|---|---|---|
| feed | string | yes | Feed id |
| window | string | – | Window (default 30d) |
No output schema declared.
No examples provided.
hello_aigent_list_feeds ~62
List the feeds you own (id, title, topics, latest_seq, discovery URL). With a workspace API key, lists only that workspace's feeds; with the admin token, lists every feed. Requires a workspace API key or the admin token.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
hello_aigent_overview ~71
Overview for a feed: subscribers, fetches today, 7-day return rate, signed-update count, a fetch sparkline, and recent agent-attributed activity. Requires a workspace API key (for a feed your workspace owns) or the admin token.
| Name | Type | Req | Description |
|---|---|---|---|
| feed | string | yes | Feed id |
No output schema declared.
No examples provided.
hello_aigent_publish ~172
Publish a signed update to a feed. The server Ed25519-signs the envelope; subscribed agents verify it before acting. Uses the feed's own publisher token, a workspace API key (for a feed your workspace owns), or the admin token. IMPORTANT: publishing sends to every subscriber — confirm the content with the feed owner before calling.
| Name | Type | Req | Description |
|---|---|---|---|
| actions | array | – | Callable actions (name, endpoint, input_schema) |
| body_markdown | string | yes | Markdown body of the update |
