mcp-server · decisionrules — Claude Code MCP server: DecisionRules rules
Wires your agent into the DecisionRules engine so decision tables, rule flows and business logic can be built and tested from the chat.
claude mcp add --transport http mcp-server https://api.decisionrules.io/mcpWhat mcp-server does
This MCP server from DecisionRules exposes the business rules platform to your coding agent. You edit decision tables, assemble rule flows and check logic without leaving the editor. Handy when the rules live in DecisionRules and the surrounding code lives in your repo.
It is a remote HTTP server at https://api.decisionrules.io/mcp, so there is no local process to run. Cursor and GitHub Copilot take a JSON block in their config; the other clients need a single terminal command.
You still need a DecisionRules account and authorization — the connection alone gets you nothing. Beyond Claude, the server is listed for Codex, Cursor, Copilot, Windsurf, Cline, Zed and Gemini CLI.
What it helps with
- spin up a decision table from a plain-language description
- edit a condition inside a rule flow without opening a browser
- run a test case through a rule and read the output
- move logic out of application code into DecisionRules
- check whether a platform rule still matches what the service does
Example prompts for the agent
- Create a decision table in DecisionRules for order discount by amount and customer type
- List the rule flows in this project and find the one handling the limit check
- Run this case through the rule and tell me what comes out
