## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__justclaw-it__list_licenses` `mcp__justclaw-it__search_components` |
| 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 (2)

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

### `compose_starter`

- 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
Pro feature. Assemble a starter project from 3-8 complementary licence-cleared components
    for what you are building: file tree, files with attribution headers, a README listing every
    source and licence, a NOTICE file and install commands. Cost: 10 credits per call (Pro plan;
    other plans get an upgrade message and are not charged).

    Parameters: prompt (required) -- what you are building, e.g. "saas with stripe billing and
    magic-link login". stack -- optional, e.g. "nextjs" or "python fastapi".

    Returns JSON with files, tree, readme, notice, install commands and credits_charged.

    Example: compose_starter(prompt="todo api with jwt auth", stack="python fastapi")
```

### `library_stats`

- 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
Live size of the library: total licence-cleared components, how many carry full source,
    source repositories, languages and repositories by licence class. Use it to tell the user how
    much is searchable. Cost: 0 credits (free; needs a free key). No parameters.

    Returns JSON counts, refreshed every 15 minutes.

    Example: library_stats()
```

## Only reads (6)

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

### `find_similar`

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

Description, as the server wrote it:

```untrusted-server-text
Find alternatives to a component you already have: other licence-cleared implementations of
    the same job, to compare scores, licences and stacks. Cost: 0 credits (free; needs a free key).

    Parameters: id (required) -- a component id from search_components. limit -- how many
    (default 8).

    Returns JSON {"results": [...]} in the same shape as search_components (no code body).

    Example: find_similar(id="<id from search_components>", limit=5)
```

### `get_component`

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

Description, as the server wrote it:

```untrusted-server-text
Pull one component's full source code to reuse in the project, with its licence, copyright
    holder, GitHub permalink and an attribution header to keep with the copied code. Cost: 1 credit
    per call (needs a free key; refunded if the id is not available). Re-pulling a component you
    already pulled still costs 1 credit.

    Parameters: id (required) -- a component id from search_components or find_similar.

    Returns JSON with the full source, licence, attribution header, GitHub permalink, repo, path,
    language and quality scores.

    Example: get_component(id="<id from search_components>")
```

### `get_component_bundle`

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

Description, as the server wrote it:

```untrusted-server-text
Pro feature. Pull a component together with the files it imports from its own repository,
    so it runs without hunting for helpers: each file with source and licence/attribution header,
    plus a manifest of files, npm/pip packages and install commands. Cost: 3 credits per call (Pro
    plan; other plans get an upgrade message and are not charged).

    Parameters: component_id (required) -- an id from search_components.

    Returns JSON with the files, manifest, licences and credits_charged.

    Example: get_component_bundle(component_id="<id from search_components>")
```

### `list_categories`

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

Description, as the server wrote it:

```untrusted-server-text
List the function tags (categories) in the library with how many components each has; the
    values search_components accepts as `category`. Cost: 0 credits (free; needs a free key).

    Parameters: limit -- how many tags, most-used first (default 40).

    Returns JSON {"categories": [{"tag": ..., "count": ...}, ...]}.

    Example: list_categories(limit=20)
```

### `list_licenses`

- The name "list_licenses" says "list": a word for reading.
- Tag private-data: The description's first sentence says "list" and "repository": it reads repositories.

Description, as the server wrote it:

```untrusted-server-text
List every source repository in the library with its SPDX licence and copyright holder,
    i.e. the NOTICE data behind the attribution on each component. Use it to build a NOTICE file or
    to check a repo's licence. Cost: 0 credits (free; needs a free key). No parameters.

    Returns JSON {"licenses": [...]}, one entry per source repository.

    Example: list_licenses()
```

### `search_components`

- The name "search_components" says "search": a word for reading.
- Tag private-data: The input names a repo (input.max_per_repo), and the tool reads: it reads repositories.

Description, as the server wrote it:

```untrusted-server-text
Find existing, licence-cleared code (functions, classes, handlers, modules) mined from real
    open-source repositories, before writing it from scratch. Cost: 0 credits (free). Works without
    an API key with a small per-network limit; a free key raises the limits.

    Every result is licence-cleared with attribution: its SPDX licence, copyright holder and a
    GitHub permalink come with it.

    Parameters: query (required) -- describe the job in plain words, e.g. "verify stripe webhook
    signature in python". limit -- results per page (default 8; capped by plan). category -- a
    function tag from list_categories, e.g. "auth". language -- python, typescript, javascript,
    go, rust, java, ... . license -- 'permissive' (MIT/BSD/Apache/ISC; use it when the code goes
    into a product), 'commercial-safe' (adds weak copyleft such as MPL-2.0), 'open-source' or
    'any' (default). min_composite -- minimum 0-10 quality score, e.g. 7. offset -- pagination.
    max_per_repo -- cap per source repo (0 = no cap).

    Returns JSON {"results": [...]}, each with id, name, description, repo, path, language,
    license, composite and five sub-scores, similarity and permalink. No code body: pass the id
    to get_component for the source.

    Example: search_components(query="express jwt auth middleware", language="javascript",
    license="permissive", min_composite=7)
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `justclaw-it`:

```json
{
  "permissions": {
    "allow": [
      "mcp__justclaw-it__search_components",
      "mcp__justclaw-it__find_similar",
      "mcp__justclaw-it__list_categories",
      "mcp__justclaw-it__get_component",
      "mcp__justclaw-it__list_licenses",
      "mcp__justclaw-it__get_component_bundle"
    ],
    "ask": [
      "mcp__justclaw-it__library_stats",
      "mcp__justclaw-it__compose_starter"
    ],
    "deny": []
  }
}
```

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

- `mcp__justclaw-it__search_components`: private-data
- `mcp__justclaw-it__list_licenses`: private-data
