How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Distill to help me. It is a free service with an MCP server at https://data.spencermcw.com/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:
- tax_sales_rate: From the state’s own Streamlined Sales Tax rate and boundary files (24 states: AR, GA, IA, IN, KS, KY, MI, MN, NC, ND, NE, NJ, NV, OH, OK, RI, SD, TN, UT, VT, WA, WI, WV, WY). Matches an address when the state publishes address records, else the ZIP+4 record, else the 5-digit rec
- tax_sales_rate_batch: The same answer as tax.sales_rate for each location, in order. A location that fails (outside the SST states, a bad date) carries its own error; the call is still one price. Price: $0.1 per call. Free tier: 3 free calls a day per IP, at most 3 rows per answer. Confidence: The low
- tax_changes: Change records read from the states’ rate and boundary files: rates that change, begin or end; ZIP+4 and 5-digit ZIP ranges whose jurisdictions change; new files posted. Each record cites the sha256 of the files it came from. Pages of up to 100, oldest first; pass next_cursor bac
- hospital_prices: From the machine-readable standard-charge files hospitals must publish (45 CFR 180), parsed and normalized: for each hospital within the radius that posts the code, nearest first, the gross charge, the discounted cash price, the de-identified minimum and maximum, and every payer 
- hospital_compare: For each named hospital: whether it posts the code, and over its items for the code (only those without modifiers when it posts any, so a professional -26 or bilateral -50 line does not skew the row) nearest-rank statistics of its gross charges, discounted cash prices and negotia
- hospital_payers: Every payer’s negotiated dollar amounts for the code at the hospitals within the radius, grouped by canonical payer_id (the stable id behind the many ways hospitals write a payer’s name), plan type and methodology (a per diem and a case rate are never pooled): how many hospitals 
- hospital_changes: Change records from diffing consecutive weekly builds: a hospital republishing its file (source raw_sha256), items and payer rates that appear, disappear or change price, a hospital’s status or file date changing, and the canonical payer of a payer/plan name changing.
