Claude Code: ask. ### `coverage` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Coverage facts: CMBS universe denominators, field inventory with definitions, current-only temporal scope, bonds=0 planned, and denominator-safe confirmation stats. Agreement/conflict rates use dual-sourced receipts only; single-source share is separate. Call before interpreting UNVERIFIED. Contact cairn@cmdrvl.com for deeper coverage/history/bonds/entitlements. ``` ### `quickstart` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Compact capability manifest for clients: purpose, workflow, routing table, examples, vocabulary guard, scope caveats, next actions, and contact. Use when new or context is tight; call coverage for coverage facts. ``` ### `verify_appraised_value` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Verify issuance appraised value (Annex A vs ABS-EE). Date/basis mismatches return DATE_INCOMMENSURATE or BASIS_INCOMMENSURATE, not CONFLICT/DENY. Until upstream shards exist, returns UNVERIFIED. ``` ### `verify_building_size` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Verify issuance building size (Annex A vs ABS-EE). Units matter: mismatched units return receipt status UNITS_INCOMMENSURATE, not CONFLICT/DENY. Until upstream shards exist, returns UNVERIFIED. ``` ### `verify_claims` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Bulk claim-set verifier: messy text in, structured evidence + disagreement out. ASSERTIONS ONLY: a QUESTION ('is it $9.4M?') binds nothing and returns total 0 — route single-value questions to verify_loan_field / verify_deal_field. Extraction is a DETERMINISTIC rule-based grammar — no model judgment. Checkable (four pattern families): (1) loan fields ('loan 25 ending balance is $9.4M'), (2) deal/pool fields, (3) servicer identity, (4) loan-status counts ('3 loans specially serviced'). Unmapped text is ENUMERATED in unchecked_spans, never silently dropped. EXACT deal references (id, alias, or CIK) adjudicate best — ranked/fuzzy resolution is never used. Statuses are ANSWERS (verified / contradicted / insufficient_evidence / out_of_scope); isError only on system failure. Each claim carries a stable claim_id, receipt-backed citations (label + receipt_sha256 + permalink URL), and evidence-calibrated confidence. ``` ### `verify_deal_field` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Verify a DEAL-GRAIN pool-level dual-sourced field against the primary SEC filings — the ABS-EE loan-tape rollup (SUM across the pool) vs the 10-D trustee's directly-reported deal fact. These are COLLATERAL (loan-pool) balances/flows, NOT outstanding bond/certificate balances, and they distinguish SCHEDULED from ACTUAL. No loan_id (the subject is the whole deal; loan_id is null). Always serves the CURRENT period held for that deal/field (the deal-grain 10-D snapshot can trail the loan tape). Returns `claim_verdict` + an sf-receipt Observation Receipt (confirmation + bound definition + value_type). Unknown deal / field returns UNVERIFIED (honest-absent). ``` ### `verify_ending_balance` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Thin alias for verify_loan_field(field='ending_balance'): verify a CMBS loan's TRUST-LEVEL securitized ending balance — the balance of this loan's note in THIS trust as reported in the 10-D and ABS-EE. NOT the whole-loan balance. Always serves the CURRENT balance; the receipt STAMPS its as-of. Returns `claim_verdict` + an sf-receipt Observation Receipt. Prefer verify_loan_field for other fields; this alias is kept for compatibility. ``` ### `verify_fund_holding_coupon` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Verify the NPORT cross-filer annualized coupon rate (`annualized_rate`) for one security identifier. The receipt is security-grain and N-source: citations are peer NPORT-P filings by registrant CIK, including dissenting parties and SEC accessions. Serving is CURRENT-ONLY: each public receipt is the latest NPORT period exported for that security. `security_id_source` may constrain the match to isin, cusip, other, ticker, or any; ticker-sourced matches join but are not unique, so set `require_hard_identifier=true` when a claim needs ISIN/CUSIP/other identity. ``` ### `verify_loan_field` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Verify a LOAN-GRAIN dual-sourced field of a specific CMBS loan against the primary SEC filings (10-D remittance + ABS-EE tape). All values are TRUST-LEVEL — this trust's securitized piece only, NOT the whole-loan balance (pari passu companions, B-notes, mezz outside the trust are excluded). Always serves the CURRENT period — the latest filing held for that deal/field; the receipt STAMPS its as-of. Returns `claim_verdict` (CONFIRM/DENY/CONFLICT/UNVERIFIED — any `claimed_value` adjudicated against the canonical value within the ledger tolerance; date fields match exactly) plus an sf-receipt Observation Receipt whose `confirmation` says whether the two filings agree, and whose subject carries the field's bound definition + value_type. Unknown deal / loan / field returns UNVERIFIED (honest-absent), never a guess. ``` ### `verify_servicer` - Nothing in its name or description says what it does, so it is counted as a write. - The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class. Description, as the server wrote it: ```untrusted-server-text Answer 'who is the servicer on deal X' against the SEC servicer roster. Deal-grain, STRING-valued. role defaults to special_servicer (the most-asked question; the 10-D roster names it for as many deals as the master). BOTH roles are SINGLE-SOURCE roster facts (SINGLE_SOURCE, 1 citation: SEC:10-D). master_servicer is NOT confirmed against the ABS-EE tape: the tape names the PRIMARY servicer, and primary is not master (delegation/transfer), so that pair measures servicing structure, not accuracy — it rides the receipt data_note as a delegation signal. String comparison is the ledger's OWN name normalization (strip legal suffixes/punctuation, upper-case), NEVER fuzzy matching. Pass claimed_servicer to adjudicate a name (CONFIRM/DENY under that normalization). It names WHO the servicer is; it does NOT assert any loan is currently in special servicing. Unknown deal / role-not-on-roster returns UNVERIFIED (honest-absent). ``` ## Only reads (3) Looks things up and changes nothing. Claude Code: allow. ### `covered_deals` - The description's first verb is "list": a word for reading. Description, as the server wrote it: ```untrusted-server-text List the deals this server can verify (Phase 0 scope) with their CIKs, aliases, and available filing periods. Call this when you need the full covered set; use find_deals for focused lookup. ``` ### `find_deals` - The name "find_deals" says "find": a word for reading. Description, as the server wrote it: ```untrusted-server-text Search covered deals by id, trust name, CIK, aliases, shelf, vintage, or deal_ref. An EXACT query (a deal id, short name, alias, or CIK that exact-matches the canon deal registry) returns a SINGLE dominant result — proceed without further disambiguation. Fuzzy queries return a small ranked recall set. Returns compact candidate metadata, match reasons/provenance, available periods, a suggested next verification call, and the search backend used. Use this for routine disambiguation; call covered_deals only when the full covered universe is needed. ``` ### `verify_loan_status_counts` - The name "verify_loan_status_counts" says "status": a word for reading. Description, as the server wrote it: ```untrusted-server-text Answer count-claims over loan status ('N in special servicing / paid off / resolved / defeased') for a deal. Returns per-status DERIVED counts, each a DERIVED_UNCONTESTED sf-receipt whose single derivation citation (party CMDRVL:derivation/loan_status_counts@v1, source_class 'derived') carries derived_from[] = the ABS-EE tape accessions consumed. These are COMPUTED classifications (int_cmbs_confirmation__asset_activity over the ABS-EE loan tape), not values any filing reports — so confirmation is DERIVED_UNCONTESTED (single lineage) and stage caps at 'cited'. THREE status grains, never mixed: activity (active / resolved_paid_off / defeased); servicing — in_special_servicing, loans CURRENTLY with the special servicer (CREFC: transfer date set, no later master return) — the count answering 'N in special servicing'. It OVERLAPS active; never sum them. And resolution reason, for loans that already LEFT the pool (resolved_via_special_servicing and the other payoff reasons) — subsets of resolved_paid_off, NOT current counts. Pass `claimed` to adjudicate exact counts per status (CONFIRM on exact match, DENY otherwise). Unknown / uncovered deal returns UNVERIFIED. ``` ## Claude Code permissions For `.claude/settings.json`, assuming the server is installed as `receipts`: ```json { "permissions": { "allow": [ "mcp__receipts__find_deals", "mcp__receipts__covered_deals", "mcp__receipts__verify_loan_status_counts" ], "ask": [ "mcp__receipts__quickstart", "mcp__receipts__coverage", "mcp__receipts__verify_loan_field", "mcp__receipts__verify_deal_field", "mcp__receipts__verify_ending_balance", "mcp__receipts__verify_fund_holding_coupon", "mcp__receipts__verify_building_size", "mcp__receipts__verify_appraised_value", "mcp__receipts__verify_servicer", "mcp__receipts__verify_claims" ], "deny": [] } } ```
