## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__marketplace__browse_store` `mcp__marketplace__list_categories` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__marketplace__agent_publish` |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `agent_publish`

- The name "agent_publish" says "publish": a word for a change that another call does not undo.
- Tag outbound: The name "agent_publish" says "publish": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Publish a draft agent to marketplace. One call, no file creation needed. Use after agent_build when user says "publish" or "register".
```

## Changes things (23)

Creates or changes something that can be changed back. Claude Code: ask.

### `beyond_obvious`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Beyond Obvious is an answer API for AI agents: send one question and get an answer that goes past the generic one, with options and viewpoints a general model does not consider and a source for every number. Beyond Obvious starts from your question and spreads across a knowledge graph of measured findings, data series and events. Graph diffusion surfaces options and viewpoints a general model does not consider. Even when no new viewpoint applies, it returns sourced values that a general web search or model answer does not surface — every number with its source. Send only the question. Typically about 5 minutes; waits up to ~50 s, then returns an id (bx_...) - poll it with get_answer. Free phase: 1 beyond_obvious request per day per key (resets 00:00 UTC; get_answer polls are not counted). Pass your agent's api_key (ak_...); without one a new key is created and shown once. Usage is recorded per key.
```

### `call_data_api`

- The name "call_data_api" says "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call one Data API by id (from list_data_apis) with params or a short text query. mode direct (default): a ready GET request + extract spec (value, unit, period, geo mapping) so you fetch the source yourself, plus cached rows when cached. mode proxy: we fetch and return compact rows "value unit | period | geo | label" with source and license, within per-source budgets. Free Data APIs cost nothing; paid listed Data APIs answer with an x402 payment requirement. Pass your agent's api_key (ak_...) for per-agent limits.
```

Pass connector + params (per-connector params are listed in each agent card: https://agentbazaar.tech/a2a/connectors/<id>/.well-known/agent.json) or a short text. Default mode direct: returns a ready GET request + short extract spec so you fetch the source yourself (no key; cache hit -> instant rows). mode "proxy": we fetch and return compact rows (one line per row "value unit | period | geo | label | id" + source/license; format "rows" for JSON; fields / limit / latest_only shrink it), within per-source budgets.
