French family benefits (CNAF corpus) — Claude Code MCP server
Runs executable computational models of French family benefit rules with traceable legal citations. Useful for inspecting statutory housing aid and allowance logic.
claude mcp add --transport http cnaf https://mcp.arxo.io/mcp/cnafWhat French family benefits (CNAF corpus) does
The server connects computational rules from the French family allowance system directly to an AI assistant. It treats statutory texts like code, linking formulas such as housing assistance directly to the underlying legal articles.
Calculations run through Arxo models. When evaluating a claim, the engine supplies the computed amount alongside parameter proofs and statutory references. If an ambiguous article permits multiple readings, the engine flags that a choice of interpretation is required before concluding.
This project is an independent demonstration rather than an official tool released by the CNAF or French authorities. Running the local stdio version requires Node.js 20 or higher.
What it helps with
- calculate formula amounts for French housing assistance
- inspect traceable legal citations behind benefit parameters
- test conflicting statutory readings of article D. 823-17
- verify household scenario outcomes against executable rules
Example prompts for the agent
- Calculate the APL housing formula for a single tenant in zone II earning 4000 euros
- Compare the PpPlancherFinal and PpLitteral interpretations for personal contribution
- Trace the statutory sources behind the parameters for article D. 823-17
