Tensorust MCP server
Remote MCP server (Streamable HTTP) from Tensorust LLC. Nothing to install: point any MCP client at the URL. The free tier needs no key, account or OAuth; an optional Authorization: Bearer tdk_... key returns full rows.
Endpoint: https://shop.tensorust.com/api/mcp

Official MCP Registry: com.tensorust/ontology (server.json)
Glama: https://glama.ai/mcp/connectors/com.tensorust.shop/tensorust-ontology
It answers who owns and controls US organizations and property, what private lenders mark their loans at, which federal research awards cite products from banned vendors, and which buyers fall under the ROAD Act investor ban. Everything comes from public records: SEC (10-Q, BDC data sets, Exhibit 21), USAspending/FPDS, NIH RePORTER, Europe PMC, DOL Form 5500, FCC (ULS, ECFS, Form 323), FAA registry, USAC E-Rate and county property rolls in 17 counties.

Tools (32)
Ownership and control graph
| tool | what it does |
|---|---|
lookup_organization | Resolve a company or organization name to its Tensorust Ontology card: legal entity or control group, data sources, linked objects by type (homes owned, control group members, subsidiaries, FCC licenses, federal awards, E-Rate requests) and the federal rules that apply to it, with status. Free: counts and previews. full=true: every linked object and property, $0.05 per call over x402 (USDC on Base) or with a Tensorust key. |
search_organizations | Search organizations, control groups and other objects by name. |
get_object | Expand any ontology id (for example org:LOCKHEED MARTIN, cg:632693, rule:ROAD-1001) into its card. Free tier returns counts and previews; full=true returns every linked object and property. |
who_owns_home | Given a US street address and ZIP, return the owner of record and, if it is a business entity, its parent control group, how many homes the group holds and whether it is a large institutional investor under the ROAD Act (350+ homes). |
rule_coverage | List the federal rules Tensorust models (ROAD Act investor ban, DoD SF 328 ownership disclosure, FCC foreign adversary attestation, Upper C-band elections, E-Rate deadlines) with counts and the first organizations each applies to. |
aircraft_owner | Look up a US turbine aircraft by N-number (or search by registered owner name): registered owner, whether it is held by an owner trustee, model, and its FCC radio altimeter rebate category and proposed rebate. |
Private credit (BDC loan marks)
| tool | what it does |

lender_marks | Private credit marks for a US company: every BDC (business development company) fund that holds its first-lien term loan, the fair value each reported as a share of par in its 10-Q for 2026-06-30 (SEC filings), the manager (Ares, Blue Owl, Goldman, Golub, Apollo...) and how far the lenders disagree. A low mark by one manager tends to lead: lenders 10-20 points above the lowest peer cut by 5+ points the next quarter 20.4% of the time vs 2.8% when lenders agree. Free: lowest and highest manager mark, the gap and three funds. full=true: every fund's mark, par, prior-quarter mark and filing link, $0.05 per call over x402 (USDC on Base) or with a Tensorust key. |

exposure_workspace | The exposure report for a private Exposure Ledger workspace (created at https://shop.tensorust.com/exposure/workspace): every stored vendor payment / PO line re-scored against today's lists, totals by vendor and rule, prohibited-use and review lines, and the join to the ledger (corroborated awards; ledger awards with no purchase line). Needs the workspace token (xlw_...). Free. |
exposure_dbgap | NIH controlled-access (dbGaP) human studies whose sequencing runs in ENA were made on BGI/MGI instruments (DNBSEQ, BGISEQ, MGISEQ), each joined to its NIH grant (from the dbGaP study record, or an identical-title NIH RePORTER project), with the grantee, PI, project end date, RePORTER award amounts and the ledger's rule status (BIOSECURE no-grace, UFLPA import presumption since Oct 29 2026).

Clearinghouse (FCC Upper C-band and rip-and-replace claims)
| tool | what it does |
|---|---|

Duplicate rules compare the claims in the call with each other. Returns per claim the verdict (accepted / review / rejected), the amount, and every rule hit with its reason and the record compared, plus totals and hits per rule. all=true adds the passing rules. Nothing is stored. Limit: 30 calls a minute and 2,000 claims an hour per IP. |
