Overview

What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • what_runs_where

    Which Claspine capabilities exist on Claspine Atlas, the self-hosted engine (any language over HTTP) and self-hosted Spring Boot. Check this before planning any Claspine integration: they differ (for example, Claspine Atlas has no sign-in, permissions or push).

  • plan_integration

    An exact, ordered plan for adding Claspine to this project: what the person must do first, then each step with the files and settings to change (current release pinned) and how to prove it worked. Call it after you know the stack, new or existing, and the person's decisions (Atla

  • search_docs

    Search Claspine's guides, recipes, capability table and error fixes with a plain question or keywords. Returns the best matches first, with links; follow up with get_guide or get_recipe.

  • get_guide

    The full text of one Claspine guide: steps, code, settings, safety notes and troubleshooting.

  • get_recipe

    Copy-ready HTTP calls for a common task on Claspine Atlas or the self-hosted engine, in curl, Node.js, Python, Go or Java, checked against Claspine's API on every build. Without task: the list.

  • upgrade_notes

    Every Claspine upgrade note after one version up to another, oldest first, with what changed, the checklist for product code and what to do before deploying. Read them all before changing the Claspine version.

  • check_upgrade

    Finds the Claspine version in project files (pom.xml, build.gradle, package.json, docker-compose.yml) or takes it as given, and lists the checklist items of every upgrade note up to the target.

  • api_reference

    The published HTTP contract shared by Claspine Atlas and the self-hosted engine (paths under /api/v1). Without path: every operation. With path (and method): parameters, request body and responses with schemas resolved.

  • java_api

    The public Java types of a Claspine capability (its api package) and of the foundation, with methods and record fields, from the current platform build. Without arguments: the capabilities.

  • explain_error

    What a Claspine error code means and how to fix it: HTTP status, the messages it is raised with, where, and the fix for common ones. Every Claspine error response carries its code.

  • check_code

    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

  • check_config

    Checks application.yml / application.properties or the engine's environment variables: empty values that switch providers on, sandbox sign-in in STAGING/PRODUCTION, IP addresses as hosts, secrets written into settings, and misspelled setting names. Content is not stored.

Common questions

Is Claspine safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.31.0) reached the registry 14 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?
