Provides official LLC formation fees, annual report deadlines, recurring costs, and name-availability checks for all 50 states and DC. Helps small business owners compare where to form an LLC and understand state-specific requirements and costs.

Example request: "Show me the cheapest states to form an LLC and what the first-year costs would be."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use FilingDesk Data to help me. It is a free service with an MCP server at https://filingdesk.com/api/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- get_llc_fees: Official LLC formation fee, recurring annual-report/franchise-tax cost, processing time, and known gotchas for a single US state, each with its source URL. Covers all 50 states + DC.
- compare_llc_costs: Rank states by what an LLC actually costs. Compares the one-time formation fee, the recurring state cost, and the combined first-year total. Use this for 'cheapest state to form an LLC' style questions rather than guessing.
- get_annual_report_deadline: Work out when a state's annual report or franchise tax is next due, the amount owed, and the late penalty. States that key the deadline to the formation anniversary or quarter need formationDate; without it the tool says so instead of guessing a date.
- check_llc_name: Check a proposed business name against a state's live registry. REAL results for Wyoming and Delaware only; Florida returns a Sunbiz search link; all other states return unsupported. A verdict is an indication, never a reservation — always show the returned note and verifyUrl.
- list_filing_states: What FilingDesk can do per state: which states it files in today with all-in pricing, which states have real name-checking, and confirmation that fee/deadline data covers all 50 states + DC. Call this before telling a user FilingDesk can file somewhere.
- compare_formation_options: Factual tradeoffs to help someone decide WHERE to form or WHAT entity type to pick. Returns fixed comparative facts and a required disclaimer — deliberately NOT a recommendation. Present the options neutrally, relay the disclaimer, and let the user choose; a FilingDesk specialist
- preview_order: Build an exact order summary WITHOUT submitting anything. No side effects. Validates the details, prices the order, and returns a confirmation summary. ALWAYS call this and show the user the returned summary before calling submit_order.
- submit_order: Submit a real formation order to FilingDesk. THIS HAS A REAL-WORLD EFFECT: it creates an order and notifies a FilingDesk specialist. Only call after preview_order and after the user has explicitly confirmed the summary. Nothing is charged now — a specialist reviews the order, ver
