What the code does

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.

        comp = subprocess.run(["iverilog", "-g2012", "-o", str(d / "sim"),

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.

run in your terminal
claude mcp add neosyn-fpga-mcp -- uvx neosyn-fpga-mcp

This one needs environment variables set before it will start: CG_JAR (Path to the C⏚ compiler jar (cg-language-server.jar). Download the prebuilt jar from the cg-compiler GitHub releases.). The author declared them in the registry entry; get the values from the project itself.

Neosyn Fpga MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Neosyn Fpga MCP?
Neosyn Fpga 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 pypi package neosyn-fpga-mcp.
How do I connect Neosyn Fpga 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 neosyn-fpga-mcp straight from pypi; nothing to host, nothing to sign up for.
Is Neosyn Fpga MCP open source?
Yes — it is published under the MIT licence, written in Python 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.
