Mcp Rpn
Let your coding agent evaluate RPN (reverse Polish notation) stacks during scripts, prototypes, or quick numeric checks without leaving the chat.
Overview
io.github.daedalus/mcp-rpn is a MCP server for the Build phase that exposes a reverse Polish notation calculator over stdio for coding agents.
What is this MCP server?
- Exposes an RPN calculator over MCP stdio (PyPI package mcp-rpn v0.1.1).
- stdio transport fits local agent configs without hosting a separate HTTP service.
- Lightweight numeric helper for stack-based expression evaluation in agent workflows.
- Open-source on GitHub (daedalus/mcp-rpn) with MCP server.schema.json metadata.
- Suitable as a teaching or debug aid when agents reason about postfix notation.
- Server version 0.1.1 on PyPI identifier mcp-rpn
- Transport type stdio per MCP server.schema.json
- Single package entry in official MCP metadata
What problem does it solve?
Agents often guess at stack-based or multi-step arithmetic unless you give them a real calculator tool wired into the session.
Who is it for?
Indie builders who want a tiny, local MCP utility for postfix math while prototyping CLIs, agents, or embedded-style logic.
Skip if: Teams that need CAS, graphing, currency units, or production billing math—use a dedicated math or finance integration instead.
What do I get? / Deliverables
After you register the stdio server, your agent can call RPN calculator tools for consistent numeric results during build and debug work.
- Registered stdio MCP server entry for RPN calculator tools
- Agent-callable stack-based arithmetic without custom plugin code
Recommended MCP Servers
Journey fit
Calculator tooling lands in Build when you wire agent-side utilities next to code generation and local automation. Agent-tooling is the right shelf because this is a stdio MCP server meant to be registered in Claude Code, Cursor, or Codex—not a standalone app feature.
How it compares
MCP integration for RPN arithmetic, not an agent skill or a full scientific computing library.
Common Questions / FAQ
Who is io.github.daedalus/mcp-rpn for?
Solo developers and agent users who want stack-based calculator tools inside Claude Code, Cursor, Codex, or other MCP clients.
When should I use io.github.daedalus/mcp-rpn?
Use it during Build when you need exact RPN evaluation while scripting, explaining postfix notation, or validating numeric agent outputs.
How do I add io.github.daedalus/mcp-rpn to my agent?
Install the PyPI package mcp-rpn (v0.1.1), add a stdio MCP server entry in your client config pointing at that command, then restart the agent session.
