Find Receipts in a directory

These listings point to the same public server. Checked November 7, 2026.

Try a sample prompt.

Connect Receipts first, then paste one of these into your AI assistant. Include the claim you want checked, rather than asking the server to look up a value.

Start with a checked claim

Sample prompt

Use Receipts verify_claims to check this statement: For WFCM 2020-C58, loan 25 has a current note rate of 4.11%. Show the result, filing period and cited sources.

Checked November 7: verified for October 2026, with two cited sources. A later filing can change a later result.

Check a passage, including its gaps

Sample prompt

Use Receipts verify_claims to check this passage: For WFCM 2020-C58, loan 25 has a current ending balance of $9,399,496.50. The property will outperform next year. Show each claim result and all unchecked spans.

Checked November 7: the balance claim was contradicted for October 2026. The forecast was left unchecked. No replacement balance was returned.

Check coverage before you begin

Sample prompt

Use Receipts quickstart and coverage. Explain which CMBS deals and fields are covered, what current-only means, and which requests the server cannot check.

Use the returned coverage and filing periods. Missing coverage does not make a claim false.

Which tool should I use?

Start with verify_claims for a passage. Use a field tool when you already know the deal, field and value you want to check.

Selected tools from the live server, checked November 7, 2026. quickstart returns the full list.
Tool	Use it to
quickstart	See how to use the server and choose a tool.
coverage	Check covered deals, fields, periods and limits.
verify_claims	Check supported claims in a passage and list unchecked text.
find_deals	Resolve a covered deal name, CIK or alias. This does not search for loans by investment criteria.
verify_loan_field	Check a claimed loan value, such as a note rate or trust-level balance.
verify_deal_field	Check a claimed pool-level collateral value.
verify_fund_holding_coupon	Check a claimed fund-holding coupon using N-PORT evidence. This is separate from CMBS coverage.

Checked 2026-11-02

A rejected claim and an unchecked forecast

The server used filing period 2026-10. This is a recorded result; call coverage before checking another claim.

Input to verify_claims

For WFCM 2020-C58, loan 25 has a current ending balance of $9,399,496.50. The property will outperform next year.

Result: contradicted

The server returned contradicted for the October 2026 ending_balance claim, which checks scheduled trust balance. A value in another balance column would not verify this field. It left the forecast in unchecked_spans and did not disclose a replacement balance.

What was not checked

The property will outperform next year

Reason: no_grammar_match. A forecast is not a supported filing fact.

Open this claim check

The linked claim check returned DENY with receipt: null. A rejected claim does not reveal the underlying value. New filings can change a later result.

Checked 2026-11-02

A note-rate claim with two agreeing sources

Both filings report the claimed rate for 2026-10. The receipt names the field, period and sources; later filings can change a later check.

Input to verify_claims

For WFCM 2020-C58, loan 25 has a current note rate of 4.11%.

Result

verified

Both cited filings report a note rate of 4.11% for the October 2026 period. verify_claims returned verified. The linked receipt reports CONFIRMED source agreement and a cited stage. This checks that field and period, not the loan's performance or investment merit.

Why the tape and the 10-D can disagree

Keep the field, reporting period and cited filings with the result. This connector contributes source citations, supported checks and explicit gaps; it does not verify every claim in a passage. Continue with the task guides to find and query related records.

Explore WFCM 2020-C58 on DealCharts for the deal page and its public filing context. Check the field and period before comparing a displayed value with a Receipts result.

Read the right result.

verify_claims reports on the full passage. The other verify tools check one claim at a time. The claim verdict judges your claim. The receipt records the cited sources and whether they agree.

Passage results

verified

The claim matches the current filing data.

contradicted

The claim does not match the filing data.

insufficient_evidence

The server could not tie the claim to one deal or loan, or the sources disagree.

out_of_scope

The deal, loan, or field is not covered.

unchecked_spans

The server could not turn this text into a claim it knows how to check. It was not checked.

Single-claim results

CONFIRM

The claim matches the source.

DENY

The claim does not match the source. DENY is only used for a claim, never for a source.

CONFLICT

The sources disagree.

UNVERIFIED

The subject is covered, but the available evidence cannot confirm the claim. It does not mean the claim is false.

OUT_OF_COVERAGE

The requested subject or field is not held. It does not mean the claim is false.

What it can and cannot check.

We checked coverage on 2026-11-07. The server supports 34 fields for CMBS deals, loans, and servicers.

Current sources

The passage tool checks CMBS facts from SEC ABS-EE and 10-D filings. Another tool checks N-PORT coupon data by security ID.

Current only means the latest filing period in the server. You cannot request an older period from this public endpoint.

verify_claims checks facts it knows how to read. Opinions, forecasts, and unsupported fields go into unchecked_spans. The server does not guess.
Monthly checks use the latest filing period held for each deal. Issuance checks use facts as of securitization. Read the date on the receipt.
Bond and class receipts are not available yet. The coverage tool reports zero.
A loan balance is the balance held by that trust. It may not be the full loan balance.
A claim is required. Rejected claims do not return replacement values or a receipt; receipt links must include the claimed value.
This tool checks sources. It does not give investment advice and does not replace human review.

Questions about Receipts

What is a CMBS MCP server?

It connects an AI assistant to commercial mortgage-backed securities tools through the Model Context Protocol. Receipts checks supported claims against public filings. Start with quickstart to see its tools.

Is this CMBS MCP server free?

Yes. The public Receipts endpoint requires no account or API key. Your AI client's own plan and workspace rules still apply.

Can I use Receipts with Claude, ChatGPT or Cursor?

Receipts uses Streamable HTTP. Setup notes for those clients are above, with a link to each vendor's instructions and an explicit test status. Claude Code and Codex commands are also provided.

Can I search for CMBS loans or screen for distress?

Receipts needs a claim to check. It does not provide a loan screener or distress index, and it does not return a replacement value when it rejects a claim. find_deals helps resolve a covered deal's identity.

How current is the CMBS data?

Monthly checks use the latest filing period held for each deal. Read the period on the result; it can differ by deal. Issuance checks use facts as of securitization. Historical timelines and bond/class receipts are not served by this endpoint.

What happens when a claim cannot be verified?

UNVERIFIED means the subject is covered but the available evidence cannot confirm the claim. OUT_OF_COVERAGE means the requested subject or field is not held. Neither means false. The passage tool also lists text it could not parse in unchecked_spans.

Coverage and freshness

Current-only CMBS claims supported by public ABS-EE and 10-D filings. Counts on this page are dated snapshots; call coverage for current deals, fields and filing periods.

Limits

Opinions, forecasts and unsupported fields remain unchecked. Read unchecked_spans.
Current-only coverage does not provide historical-period queries.
Bond and class receipts were unavailable in the 2026-11-02 coverage check.
A loan balance is the trust's securitized balance and may differ from the whole-loan balance.
UNVERIFIED means covered but not confirmable. OUT_OF_COVERAGE means nothing is held for the requested subject or field. Neither means the claim is false.
A claim is required. This verification service is not a loan-lookup API or a distress-index server.
A rejected claim does not disclose the underlying value. Receipt links require the claimed value to check.
Source checks do not replace human review or provide investment advice.
