## 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__tako__tako_available_data` `mcp__tako__tako_contents` `mcp__tako__tako_graph_related` `mcp__tako__tako_search` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__tako__tako_contents` |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `tako_graph_related`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Explore what a graph node connects to — its metrics, the entities a metric covers, competitors, industry, index membership, and sources.

Two modes. Pass `node_id` alone for the map: every relation group with its key, label, total, and its first 3 names. Pass `relation` to page one group, where each item comes back with the id that explores it. Read a key off the map rather than guessing — an unknown key returns an empty group, not an error.

Best for: expanding a node you already resolved. Resolve a name to a node id with `tako_available_data` first. A metric listed here means the graph tracks it, not that a card exists — `tako_search` is the final check.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `tako_available_data`

- The description's first verb is "find": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Find what data Tako holds on an entity or a metric, and the canonical name it holds it under.

Best for: coverage questions themselves, or a metric's canonical name before a priced search. Put a company, person, or place in `q` to list the metrics tracked on it; put a metric in `q` to list the entities it covers. Add `metric` when you know the measure — you get the resolved pair and a ready-to-run `next_call`.

Search on the canonical names it returns, not your own phrasing — `tako_search` matches the graph's names, not yours. A name here means the graph tracks it, not that a card exists. If the follow-up search comes back empty, say Tako has no card for it rather than rephrasing the query. Hand a node id to `tako_graph_related` to see what else connects to it.
```

### `tako_contents`

- The description's first verb is "fetch": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "fetch" and "url": it reads web pages, which anyone can write. The input takes a URL (input.urls), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.urls): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Fetch the full content behind a url: a web page's text, or an exportable Tako card's data rows. Batch up to 10 urls in one call — each one is billed and fails on its own.

Fetch only cards that `tako_search` marked `exportable: true`. Rows bill per 1,000 delivered, so set `max_rows` when the recent rows are enough. A website-traffic or SEO card also bills a per-unit data minimum that `max_rows` doesn't bound. If a page is long, such as a filing or an annual report, set `query` to a question to get back only the passages that answer it.

Best for: reading one source in full — a page you need to quote, or the rows behind a card you need to compute over.
```

### `tako_search`

- The name "tako_search" says "search": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "search" and "web": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Search Tako's data graph and the live web in one call: many results at once, as structured cards plus web results, with the top card rendered inline as a chart.

It finds data; `tako_contents` fetches it. Each card carries a headline value, node ids, and a url — pass the url to `tako_contents` for rows (`exportable: true` cards) or a web result's full page text. When `exportable` is false the rows are locked — read the headline value from the card's `description`. Website-traffic and SEO cards bill a per-unit data minimum above the search price.

Best for: breadth — fan out several narrow queries in parallel. Each query resolves one metric — for one entity, or a comparison set ("Apple revenue", "Nvidia vs AMD gross margin"); several metrics or topics in one query retrieve poorly. To learn what Tako covers, or a metric's canonical name, run `tako_available_data` first, then search on the canonical name it returns.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `tako`:

```json
{
  "permissions": {
    "allow": [
      "mcp__tako__tako_available_data",
      "mcp__tako__tako_search"
    ],
    "ask": [
      "mcp__tako__tako_contents",
      "mcp__tako__tako_graph_related"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__tako__tako_available_data`: untrusted-input
- `mcp__tako__tako_contents`: untrusted-input, outbound
- `mcp__tako__tako_graph_related`: untrusted-input
- `mcp__tako__tako_search`: untrusted-input

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.tako.com/mcp: tools/list returned 4 tools to an anonymous client, including tako_graph_related (write)
