## Exfil surface

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

| 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `explore`

- 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
Step 1 of the MCPYP selection funnel (broad search). Returns a broad pool of candidate servers for a task (default 20, paged with offset) plus the total match count. Use this first to see the shape of the pool, then narrow with refine. Pass the same journey_id across explore, refine, and pick so the journey is logged as one funnel.
```

### `pick`

- 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
Step 3 of the MCPYP selection funnel (final selection). Commits to exactly ONE server: either the top-ranked server for a further-improved query, or the named server from the refine step. Keep improving the query: each step's query should be sharper than the last, so the journey shows how the choice narrowed. After pick, call get_config to connect. This is the funnel's conversion point.
```

### `refine`

- 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
Step 2 of the MCPYP selection funnel (refined search). Narrows a task to exactly 5 candidates. IMPORTANT: improve the query at each step - use what explore returned (candidate names, tool names, categories) to write a sharper, more specific query here than the explore query. Optionally constrain to servers that need no publisher key (no_key_required). Call after explore, then commit with pick.
```

## Only reads (3)

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

### `find_mcp`

- The name "find_mcp" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the MCP Yellow Pages measured catalog. Start here to discover MCP servers for a task. Returns servers ranked by content match, then by independently measured quality (liveness, deep-test results, tool counts). Every result was actually probed by MCPYP; requires_key tells you whether the server needs a publisher API key before use.
```

### `get_config`

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

Description, as the server wrote it:

```untrusted-server-text
Get a ready-to-paste client configuration for one MCP server. If the server requires a publisher API key, the config contains a placeholder plus where to obtain the key; MCPYP never issues or stores keys. Pass the same journey_id as the pick step so the funnel conversion is logged.
```

### `get_mcp`

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

Description, as the server wrote it:

```untrusted-server-text
Get the full measured profile of one MCP server: description, measured tool list with parameters, liveness and deep-test outcomes, endpoint region. Use after find_mcp to inspect a candidate before connecting.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__mcpyp__find_mcp",
      "mcp__mcpyp__get_mcp",
      "mcp__mcpyp__get_config"
    ],
    "ask": [
      "mcp__mcpyp__explore",
      "mcp__mcpyp__refine",
      "mcp__mcpyp__pick"
    ],
    "deny": []
  }
}
