Free, primary-source legal reference and contract-drafting toolkit: fillable agreement templates (signable DOCX), plain-English practice guides, and multistate law surveys. Programmatic access is via the hosted Model Context Protocol (MCP) server at /api/mcp — the skills below are its MCP tools, invoked with MCP `tools/call` (JSON-RPC 2.0 over HTTP), NOT classic A2A `message/send`. MCP clients should `initialize` then `tools/list`; see documentationUrl. Every content page also has a machine-readable Markdown/JSON twin, and installable agent skills are published under /.well-known/agent-skills/.
