Juriset

Juriset MCP server

The Juriset MCP server: verified, versioned, cited jurisdiction rules for AI agents. It starts with US and Canadian employment and payroll rules (minimum wage, overtime, paid leave, termination notice, payroll contribution rates).

Every value carries its citation: the official source URL, a verbatim excerpt and the stored snapshot. Each was extracted by one model and checked blind against the primary source by a model from another vendor; escalations are reviewed by a human. Every version has a stable id (rv_…) to record with a decision, so you can show later exactly which rule applied.

Juriset reports what official sources say. It never computes an answer for a case and never merges levels of government into one rule. Informational only, not legal advice.

mcp-name: dev.juriset/juriset

Use it

Two ways in, the same eight read-only tools behind both.

Hosted, nothing to install

Streamable HTTP at https://mcp.juriset.dev/mcp. Add it as a remote MCP server in any client that takes a URL. No key is needed to try it; for your plan's limits and the key-only tools, send Authorization: Bearer jrs_live_… with a key from https://juriset.dev/account.

Claude Code: claude mcp add --transport http juriset https://mcp.juriset.dev/mcp

Local (stdio), from PyPI or npm

Needs uv (uvx) or Node 18+ (npx, which runs the same Python server through uvx).

{ "mcpServers": { "juriset": { "command": "uvx", "args": ["juriset-mcp"] } } }

Claude Code: claude mcp add juriset -- uvx juriset-mcp. With npm instead of uv: "command": "npx", "args": ["-y", "juriset-mcp"].

No account is needed to try it: without a key the API's keyless tier answers current rules, read-only, at 60 requests an hour and 500 a day per IP address. As-of queries, history and the change feed need an API key whose plan includes them. Get one at https://juriset.dev/account, then add "env": {"JURISET_API_KEY": "jrs_…"} to the config.

Variable	Meaning
JURISET_API_KEY	Optional API key, sent as a bearer token.
JURISET_API_URL	Default https://api.juriset.dev; set for staging.

Tools

All read-only. Slugs: a jurisdiction is us-wa (Washington), us (US federal), ca-ab (Alberta); a rule type is minimum_wage, overtime, …

Tool	Use it to
list_jurisdictions	Find a jurisdiction's slug from its name or postal code.
list_rule_types	See the rule types, their domains and the JSON Schema of their values.
get_rule	Get the rule in force today, with citations.
get_rule_as_of	Get the rule in force on a past or future date.
get_rule_history	List every published version of a rule.
compare_jurisdictions	Get one rule type across jurisdictions.
list_changes	Page through what changed since a date.
resolve_version	Fetch exactly the version a stored id names, forever.

Where levels of government stack (US federal and state overtime) the response lists each level as its own entry. Nothing is merged.

This repository

A read-only mirror of the published package, so you can read exactly what runs and file issues. The server is developed in the private Juriset monorepo and released from there to PyPI and npm; each release is copied here unchanged. Issues are welcome; pull requests are read but not merged directly (a fix lands in the monorepo and arrives here with the next release).

Path	What it is
juriset_mcp/	The server: __main__.py (stdio entry), server.py, executor.py (calls the public /v1 API), tools.json (the tool definitions, generated)
pyproject.toml	Builds the same juriset-mcp wheel: uv build --wheel
npm/	The npm package, a small wrapper that runs the PyPI version with uvx
server.json	The record in the official MCP Registry (dev.juriset/juriset)

Run from a checkout: uv run juriset-mcp (stdio). The server only reads from the public API (JURISET_API_URL, default https://api.juriset.dev); it stores nothing and sends nothing else.
