⚖️ Legal Peripherals MCP Server

A premium Model Context Protocol (MCP) server powered by FastMCP that exposes highly robust tools for automating legal operations and filing compliance. This server handles state-level Secretary of State (SOS) entities, off-hours compliant IRS Form SS-4 EIN drafting/scheduling, and corporate/LLC charter templates lookup.

Documentation — Installation, deployment, usage across the API and MCP interfaces, and the optional agent server are maintained in the official documentation.

🗺️ System Architecture

The following diagram illustrates how the Legal Peripherals MCP Server coordinates between external LLM clients, state Secretary of State (SOS) databases, the IRS Form SS-4 preparation engine, and local template resources:

🛠️ MCP Tools Mapping

The server registers the following standard FastMCP tools, which can be dynamically enabled or disabled via environment toggles:

Auto-generated — do not edit between the markers below.

Condensed action-routed tools (default — MCP_TOOL_MODE=condensed)

Verbose 1:1 API-mapped tools (MCP_TOOL_MODE=verbose or both)

4 action-routed tool(s) (default) · 1 verbose 1:1 tool(s). Each is enabled unless its <DOMAIN>TOOL toggle is set false; MCP_TOOL_MODE selects the surface (condensed default · verbose 1:1 · both). Auto-generated — do not edit.

MCP Configuration Examples

Install the slim [mcp] extra. All examples install legal-peripherals-mcp[mcp] — the MCP-server extra that pulls only the FastMCP / FastAPI tooling (agent-utilities[mcp]). It deliberately excludes the heavy agent runtime (pydantic-ai, the epistemic-graph engine, dspy, llama-index), so uvx / container installs are far smaller. Use the full [agent] extra only when you need the integrated Pydantic AI agent.

Additional Deployment Options

legal-peripherals-mcp can also run as a local container (Docker / Podman / uv) or be consumed from a remote deployment. The Deployment guide has full, copy-paste mcp_config.json for all four transports — stdio, streamable-http, local container / uv, and remote URL:

• Local container / uv — launch the server from mcp_config.json via uvx, docker run, or podman run, or point at a local streamable-http container by url.
• Remote URL — connect to a server deployed behind Caddy at http://legal-peripherals-mcp.arpa/mcp using the "url" key.

Deploy with agent-os-genesis

This package can be provisioned for you — skill-guided — by the agent-os-genesis universal skill (its single-package deploy mode): it picks your install method, seeds secrets to OpenBao/Vault (or .env), trusts your enterprise CA, registers the MCP server, and verifies it — the same machinery that stands up the whole Agent OS, narrowed to just this package. Ask your agent to "deploy legal-peripherals-mcp with agent-os-genesis".

Secrets are read-existing + seeded via vault_sync — you are only prompted for what's missing.
