Anlyon alternative

2 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Changes things 2Claude Code: ask
  • compose_starterPro feature.No findings

    Why it is in this group

    • 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
    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")

    Annotations the server declares

    • title: Compose a starter project (Pro)
    • readOnlyHint: true
    • destructiveHint: false

    Why it is in this group

    • 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
    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()

  • find_similarFind alternatives to a component you already have: other licence-cleared implementations of the same job, to compare scores, licences and stacks.No findings

    Why it is in this group

    • The name "find_similar" says "find": a word for reading.
    Description, as the server wrote it
    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)

    Annotations the server declares

    • title: Find similar components
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • get_componentPull 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.No findings

    Why it is in this group

    • The name "get_component" says "get": a word for reading.
    Description, as the server wrote it
    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>")

    Annotations the server declares

    • title: Get component source
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • get_component_bundlePro feature.No findings

    Why it is in this group

    • The name "get_component_bundle" says "get": a word for reading.
    Description, as the server wrote it
    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>")

    • title: Get component bundle (Pro)
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false
  • list_categoriesList the function tags (categories) in the library with how many components each has; the values search_components accepts as `category`.No findings

    Why it is in this group

    • The name "list_categories" says "list": a word for reading.
    Description, as the server wrote it
    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)

    Why it is in this group

    • The name "list_licenses" says "list": a word for reading.

    What it can reach

    • private-dataThe description's first sentence says "list" and "repository": it reads repositories.
    Description, as the server wrote it
    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()

    • openWorldHint: false
  • search_componentsFind existing, licence-cleared code (functions, classes, handlers, modules) mined from real open-source repositories, before writing it from scratch.Reads private dataNo findings

    Why it is in this group

    • The name "search_components" says "search": a word for reading.

    What it can reach

    • private-dataThe input names a repo (input.max_per_repo), and the tool reads: it reads repositories.
    Description, as the server wrote it
    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)

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

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

Reads private data2
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Remote posture

Findings

Matches of fixed checks, with the text they matched.

No check matched anything in these tool definitions. That is not a safety guarantee.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json

}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as justclaw-it. Review it before you use it.
