Claspine docs, API reference and code checks for AI agents: guides, recipes, errors, upgrades.

11 tools: 1 do something that can't be undone, 7 change things and 3 only read.

Anlyon alternative

8 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.

Why it is in this group
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
What it can reach
- outboundThe input takes a destination (input.to): what the tool writes goes there.

  The server marks "upgrade_notes" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

  What this check looks for
Description, as the server wrote it
Runs Claspine's Agent Shield rules on files or a unified diff: hardcoded or client-exposed secrets, SQL built from strings, unscoped tenant queries, secrets in logs, buffered uploads, imports of platform internals. Returns file, line, rule and the fix. Code is analysed in memory and not stored. A clean result is not proof of safety; Spring Boot builds also run ProductBoundaryTest.

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.

3 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 1 outbound tool breaks every one.

Reads private data3: Reads files, mail, messages, databases, secrets, calendars or repositories.; check_upgrade
get_guide
search_docs
Reads text others write1: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; get_recipe
Can send data out1: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; upgrade_notes

deny to break every path

{
  "permissions": {
    "deny": [
      "mcp__claspine__upgrade_notes"
    ]
  }
}

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

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 claspine. Review it before you use it.
