Install

How do I install the US compliance and books health MCP server?

US compliance and books health is a hosted endpoint at https://medianfi.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
explain_books_check ~90

Full detail on a single books health check: what it is, exactly where to look in the ledger, every innocent explanation to rule out before concluding anything, what it costs if it is real, what fixing it involves, and whether it is inside what Median does.

NameTypeReqDescription
check_idstringyesCheck id from list_books_checks, e.g. 'rec-processor-balance-unreconciled'.

No output schema declared.

No examples provided.

explain_obligation ~64

Plain-English detail on a single obligation: what it is, why it exists, the deadline, the cost, the penalty, the exact remediation steps, and the government source.

NameTypeReqDescription
obligation_idstringyesObligation id, e.g. 'de-registered-agent'.

No output schema declared.

No examples provided.

get_blog_post ~43

Fetch the full text of one published Median blog post by its slug.

NameTypeReqDescription
slugstringyesPost slug, e.g. 'how-to-switch-bookkeeping-services'.

No output schema declared.

No examples provided.

get_company_overview ~39

Who Median is, what it does, who it is for, how onboarding works, and how to get in touch or book an intro call.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

get_confounders ~797

Refinement step, NOT the place to start: call list_compliance_obligations first, then call this to narrow what is still genuinely open. Returns the facts that flip an answer, such as whether an employer of record is the legal employer. Pass every fact you already know and it returns only what those facts leave unsettled. These are things for YOU to look up in the user's own documents. They are not a questionnaire to send the user.

NameTypeReqDescription
answeredobject–Only for confounders with no matching fact field above (who-paid, prepaid-multi-year). For everything else pass the fact itself, e.g. payroll_model: 'eor', not answered: { 'payroll-model': 'eor' }.
answersobject–Answers to the yes/no threshold questions this tool asks, keyed by the threshold id shown in the question, e.g. { "foreign-accounts-over-10k": false, "ny-sales-over-500k": false }. Without this the s…
company_namestring–Optional, and the only identifying thing this tool records. Median stores it to see which companies use this tool and may follow up. It changes nothing about the answer, so omit it if the user has no…
contractor_statesarray–States where 1099 contractors work.
employee_statesarray–States where W-2 employees work.
entity_typestring–Legal entity type.
extensions_filedobject–Whether a tax extension was filed, keyed 'US' for federal and by state code, e.g. { US: true, NY: false }. OMIT a key you are unsure about: no deadline is asserted for an unknown key, because assumin…
fiscal_year_endstring–MM-DD, e.g. '12-31'. Defaults to 12-31.
foreign_owned––Whether any non-US person owns 25% or more. Leave unset if genuinely unknown.
formation_datestring–ISO date the entity was formed.
formation_platformstring–Decides whether a bundled first-year registered agent explains a missing fee.
formation_statestring–Two-letter state of formation, e.g. 'DE'.
operating_statesarray–States where the company operates.
payroll_modelstring–Critical. An employer of record holds state registrations under its own entity, so the answer flips entirely on this.
payroll_providerstring–The provider's name only, e.g. 'Deel', 'Gusto', 'Rippling'. Not account numbers, not employee details, not anything else.
presence_typeobject–Per-state presence, e.g. { NY: 'virtual-mailbox' }.
registered_inobject–Whether the company is already registered to do business in a state, e.g. { NY: false }. Drives obligations that only begin at registration.
revenue_bandstring–Gross annual revenue as a band, never an exact figure: 'pre-revenue', 'under-250k', '250k-1m', '1m-5m' or 'over-5m'. Drives revenue-scaled thresholds such as state franchise tax minimums and economic…
sales_statesarray–States with customers.
sells_saas––Whether the product is SaaS. New York taxes SaaS as prewritten software.
tax_yearinteger–Tax year under review. Defaults to last calendar year.

No output schema declared.

No examples provided.

get_evidence_recipe ~78

For one obligation, return exactly how to prove it: which sources settle the question, which are only corroborating, what each state's public registry does and does not expose, and the innocent explanations for missing evidence. Use this before concluding anything is missing.

NameTypeReqDescription
obligation_idstringyesObligation id from list_compliance_obligations.

No output schema declared.

No examples provided.

get_pricing ~68

Median's published pricing: the flat monthly fee by revenue band under $1M in annual revenue, the per-account and per-ledger-entry meter that scoping is based on above $1M, what is included, and add-on pricing for tax, R&D credits, and sales tax.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

list_blog_posts ~80

List published articles from the Median blog, newest first. Optionally filter by category or a search term matched against the title.

NameTypeReqDescription
categorystring–Filter to one category slug or name.
limitinteger–How many posts to return (default 20, max 50).
searchstring–Match against the post title.

No output schema declared.

No examples provided.

list_books_checks ~411

START HERE for a books health check. Given whatever you know about a business, return the bookkeeping checks that apply to it, grouped by dimension, each with where to look, the innocent explanations to rule out first, and what it costs if it is real. Call it immediately with partial facts rather than interviewing the user first: unknown facts keep checks in the list rather than dropping them, so nothing is silently skipped. Cash-basis businesses correctly get a shorter list. This never says whether books are correct, only what to look at.

NameTypeReqDescription
basisstring–Cash or accrual, printed at the top of most profit and loss reports. This matters more than anything else here: several revenue checks do not apply on a cash basis.
bills_aheadboolean–Whether anything is billed ahead of delivery: subscriptions, retainers, annual plans.
charges_sales_taxboolean–Whether sales tax is charged anywhere.
company_namestring–Optional, and the only identifying thing this tool records. Median stores it to see which businesses use this tool and may follow up. It changes nothing about the answer, so omit it if the user has n…
has_contractorsboolean–Whether 1099 contractors are paid.
has_raisedboolean–Whether the business has raised on a SAFE, note or priced round, or taken a loan.
ledgerstring–Which ledger the books live in. Visible in the header of any export.
needs_segment_reportingboolean–Whether any part of the business needs separate reporting: locations, programs, product lines, more than one entity.
payroll_modelstring–How people are paid.
processorsarray–Payment processors that hold a balance before paying out, e.g. ['stripe','paypal']. Names only. Drives the single most-missed check.

No output schema declared.

No examples provided.

list_compliance_obligations ~946

START HERE. Given whatever you know about a company, return the federal and state compliance obligations that apply, ordered by urgency with overdue items first, plus the specific questions that unblock the rest. Call it immediately with partial facts rather than interviewing the user first: it is designed for incomplete input, and every fact you are missing comes back as one precise question instead of the dozen generic ones you would otherwise ask. Then answer those and call it again. Defaults to a short actionable view; relay it roughly as written rather than expanding it into an essay, and pass detail='full' only when the user asks for evidence tiers and remediation detail. Covers US federal plus CA, CO, DE, FL, GA, IL, MA, NJ, NY, PA, TX and WA; every other state is reported honestly as not yet covered. This never tells you whether you are compliant, only what to check.

NameTypeReqDescription
answersobject–Answers to the yes/no threshold questions this tool asks, keyed by the threshold id shown in the question, e.g. { "foreign-accounts-over-10k": false, "ny-sales-over-500k": false }. Without this the s…
company_namestring–Optional, and the only identifying thing this tool records. Median stores it to see which companies use this tool and may follow up. It changes nothing about the answer, so omit it if the user has no…
contractor_statesarray–States where 1099 contractors work.
detailstring–Default 'brief': what applies, when it is due, and the questions, with no evidence or remediation detail. Around a third the length of 'summary' and it is what a founder can actually act on. 'summary…
employee_statesarray–States where W-2 employees work.
entity_typestring–Legal entity type.
extensions_filedobject–Whether a tax extension was filed, keyed 'US' for federal and by state code, e.g. { US: true, NY: false }. OMIT a key you are unsure about: no deadline is asserted for an unknown key, because assumin…
fiscal_year_endstring–MM-DD, e.g. '12-31'. Defaults to 12-31.
foreign_owned––Whether any non-US person owns 25% or more. Leave unset if genuinely unknown.
formation_datestring–ISO date the entity was formed.
formation_platformstring–Decides whether a bundled first-year registered agent explains a missing fee.

list_services ~38

List the services Median offers (daily bookkeeping, tax filing, R&D tax credits, CFO advisory) with a short summary and page link for each.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

score_books_health ~422

Score a books health check from the statuses you actually evidenced. Returns the weighted score, the band, a per-dimension breakdown and the findings ranked worst first. Two rules a plain average does not give you: a confirmed critical caps the grade, and the band is WITHHELD entirely when too little was evidenced, because a flattering number off three checks is the part people quote. Report the withheld state rather than supplying a band yourself.

NameTypeReqDescription
basisstring–Cash or accrual, printed at the top of most profit and loss reports. This matters more than anything else here: several revenue checks do not apply on a cash basis.
bills_aheadboolean–Whether anything is billed ahead of delivery: subscriptions, retainers, annual plans.
charges_sales_taxboolean–Whether sales tax is charged anywhere.
