## Exfil surface

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

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

## Findings

- **warn** Annotations that disagree with the tool in `how_to_run_locally` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "how_to_run_locally" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "how_to_run_locally" says "run": a word for a change.
```


## Changes things (2)

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

### `how_to_run_locally`

- The name "how_to_run_locally" says "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
How to rerun this benchmark on your own machine with your own API keys, including on your own queries. Nothing runs on this server.
```

### `recommend_provider`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Which web search API fits an agent, based on this benchmark: live voice/chat turns, deep research, semantic or long-tail queries, docs lookups, or a specific use case (GTM, insurance, finance). Returns the guidance with the supporting numbers.
```

## Only reads (9)

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

### `compare_providers`

- The name "compare_providers" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Compare two or more of You.com, Tavily, Exa and Parallel side by side, overall or within one use case, optionally filtered to metrics whose name contains a keyword (e.g. 'latency', 'accuracy', 'fresh', 'cost', 'empty').
```

### `fetch`

- The name "fetch" says "fetch": a word for reading.
- Tag private-data: The description's first sentence says "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
Full text of one benchmark document by its ID (for example question-F5, scorecard-finance, overall, methodology).
```

### `get_charts`

- The name "get_charts" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The published graphs: overall scorecard, key metrics and per-query grids for GTM, insurance and finance, and developer activation. Without chart_id, lists them with titles and image links; with chart_id, also returns the image.
```

### `get_methodology`

- The name "get_methodology" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
How the benchmark was run and graded: query design, identical request parameters, 3 runs per query, latency timing, SimpleQA and FreshQA grading, the 10 metrics and the standards they follow, and limits.
```

### `get_overall_results`

- The name "get_overall_results" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Headline findings and the overall scorecard across all 30 queries (90 calls per API): accuracy, fully correct, precision@5, freshness, empty responses, failed calls, latency p50/p95, cost per correct answer. Also the per-use-case summary, which API fits which agent, and developer activation time.
```

### `get_question`

- The name "get_question" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
One benchmark question by ID (e.g. G3, I4, F5): the task, search call, parameters, answer key with sources, and what each API returned with its accuracy score (0-2, mean of 3 runs).
```

### `get_scorecard`

- The name "get_scorecard" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Full metric scorecard for one use case (gtm, insurance, finance) or 'overall'. Metrics: search-only latency p50/p95 (server and client), calls under 1 s, accuracy, freshness (% in window, newest relevant result age), content in one call, tokens, search cost.
```

### `list_questions`

- The name "list_questions" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The 30 benchmark questions (G1-G10 GTM, I1-I10 insurance, F1-F10 finance): ID, what the agent is asked, the search call and freshness.
```

### `search`

- The name "search" says "search": a word for reading.
- Tag untrusted-input: 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 the Web Search API Eval benchmark (results, questions, methodology, charts, how to run). Returns matching document IDs, titles and URLs.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `websearch-api-eval`:

```json
{
  "permissions": {
    "allow": [
      "mcp__websearch-api-eval__get_overall_results",
      "mcp__websearch-api-eval__get_scorecard",
      "mcp__websearch-api-eval__compare_providers",
      "mcp__websearch-api-eval__list_questions",
      "mcp__websearch-api-eval__get_question",
      "mcp__websearch-api-eval__get_charts",
      "mcp__websearch-api-eval__get_methodology",
      "mcp__websearch-api-eval__search",
      "mcp__websearch-api-eval__fetch"
    ],
    "ask": [
      "mcp__websearch-api-eval__recommend_provider",
      "mcp__websearch-api-eval__how_to_run_locally"
    ],
    "deny": []
  }
}
```

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

- `mcp__websearch-api-eval__search`: untrusted-input
- `mcp__websearch-api-eval__fetch`: private-data
