Common questions
Is Helvabase — Governed response dossiers safe?
It passed 1 of 1 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?
You need to fill in: Authorization
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 2 months 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?

Helvabase plugins and connector
Published by Starbox Group Gmbh. The plugins provide workflows for sourced dossiers and human review, in French, English and German.
Install the plugin from this repository
Add https://github.com/alopez3006/helvabase-mcp as a plugin marketplace in your client, then install Helvabase and authorize your Helvabase account. Repository catalogues are available for Claude and Codex. This repository is not an official directory approval; native end-to-end acceptance remains in progress.
- Français
- English
- Deutsch
- Claude complete plugin:
plugins/claude/helvabase - Codex complete plugin:
plugins/helvabase
Plugin files are MIT licensed. Brand assets and the hosted service are excluded; see LICENSE and NOTICE.
Agent catalogue
Plugin version 1.4.8 uses https://helvabase.com/mcp?catalog=core: eight essential operations, metadata help and scoped read/write specialist execution. The packaged skills describe discovery and exact-contract invocation. Update your existing plugin and refresh its tools; changing from the previous URL can require OAuth again. Keep the same authorized account and workspace.
The complete individual catalogue remains at https://helvabase.com/mcp, including for review. No official directory acceptance is implied. Native Codex specialist reads have been verified; native Claude acceptance and full file workflows remain separate checks.
Connector configuration fallback
This repository is the public installation surface for the hosted Helvabase MCP connector. It does not contain the Helvabase application, customer data, backend credentials or a standalone replacement server.
Generate configuration
Use Node.js 20 or newer:
npx --yes github:alopez3006/helvabase-mcp \--url https://helvabase.com/mcp
The command writes codex.toml, claude.json, mistral.json and README.txt to ./helvabase-mcp-config (or the directory supplied with --out).
Authentication is completed through each client’s OAuth flow. No API key or bearer token is placed in a client configuration file.
The URL must be a deployed Helvabase HTTPS endpoint ending in /mcp. This kit does not deploy Helvabase or provide a local server. Native-client compatibility, file transfer, refresh/revocation and human-review workflows must be verified against the deployed service.
Only files under public/mcp are published from the private Helvabase repository. The source workflow syncs this directory after changes land on main. It uses a dedicated SSH deploy key with write access only to alopez3006/helvabase-mcp, stored as the source repository's MCP_PUBLICATION_SSH_KEY Actions secret. No personal GitHub token is required.
