Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Package points at a different repository fidacy/fidacy-open
пакет @fidacy/mcp ссылается на lucaslubi/fidacy-mcp
In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Runs an external command .github/smoke.mjs:7
const proc = spawn(bin, [], { stdio: ["pipe", "pipe", "inherit"] });

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: FIDACY_ENGINE_API_KEY (Required: activates the account-owned authority boundary and signed verdicts. Get a free key at https://app.fidacy.com/signup.), FIDACY_MODE (Optional: 'http' for the hosted core.). The author declared them in the registry entry; get the values from the project itself.

Fidacy MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Fidacy MCP?
Fidacy MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @fidacy/mcp was installed 255 times last week.
How do I connect Fidacy MCP?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @fidacy/mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Fidacy MCP?
The npm package @fidacy/mcp was installed 255 times in the last week. Week over week that is +2%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Fidacy MCP open source?
Yes — it is published under the Apache-2.0 licence, written in JavaScript and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
