FilingDesk Data is an MCP server with 8 tools an agent can call, among them check_llc_name, compare_formation_options, compare_llc_costs. It answers at https://filingdesk.com/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
US LLC filing fees, annual-report deadlines and naming-rule checks, from official state sources.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
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 Inputs: name, state, entityType |
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 Inputs: topic, homeState |
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. Inputs: states, sortBy, limit |
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 guess Inputs: state, formationDate |
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. Inputs: state |
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 fi |
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. Inputs: businessName, state, entityType, description, fullName, email |
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 n Inputs: businessName, state, entityType, description, fullName, email |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://filingdesk.com/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
