This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

Common questions

Is Cinderfi — Retirement Planning 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 (1.0.1) reached the registry 7 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?

Claude Code plugin

The fastest path in Claude Code — installs the MCP server plus a retirement-planning skill that sequences the tools:

/plugin marketplace add cinderfi/cinderfi-mcp

/plugin install cinderfi@cinderfi

Then set your key so the server authenticates:

export CINDERFI_MCP_KEY=your_api_key   # from https://cinder.fi/mcp

Agents that support the auth.md protocol can also register for their own credential through a user-approved claim ceremony — no pasted key required.
