Only matching statements from BOTH pinned party keys produce a signed `settled_reported_by_both` receipt. SaSame does not move funds or independently verify off-chain settlement; use a chain/processor receipt as settlement_ref when available.

The legacy tool name is retained for API compatibility: this is a transaction-confirmation receipt, not a fiscal/tax invoice. The provider signs provider_receipt_challenge (identical to the legacy provider_invoice_challenge). The receipt binds mutually accepted terms, delivery and amount. If SaSame SRL itself sells a service, its separate accounting rail issues the normal SaSame SRL business invoice.

SaSame, operated by SASAME S.R.L., continuously observes and measures the Model Context Protocol ecosystem and publishes verifiable evidence and history; the MCP Factory is internal machinery and an optional product surface behind it; measurement only, not endorsement. Raw scope/deliverables are never stored; only their SHA-256 commitments, public labels, signatures and state transitions are retained. The legacy tool name is retained for compatibility; this is not a fiscal invoice.

SaSame, operated by SASAME S.R.L., continuously observes and measures the Model Context Protocol ecosystem and publishes verifiable evidence and history; the MCP Factory is internal machinery and an optional product surface behind it; measurement only, not endorsement. Runs the legitimate revision-aware MCP protocol entry (server/discover with legacy initialize fallback), tools/list, and one read-only tool call over POST JSON-RPC. It returns the grade, a per-criterion pass/evidence breakdown, and the single biggest gap to fix. This returns the grade and analysis ONLY — if you want a signed, portable certificate of the same audit, use verify_mcp_ready instead. DIRECTORY PRE-FLIGHT: these criteria cover the MECHANICAL reject reasons of the Claude Connectors Directory and ChatGPT Apps Directory (annotations, typed schemas, description clarity, liveness, graceful errors, anti-ghost) — run it before you submit. It does NOT cover privacy-policy, identity/business verification, OAuth callbacks, or prohibited-category rules; it catches mechanical failures, it does not guarantee a pass. SECURITY SIGNALS (advisory, never a verdict): plain-HTTP exposure, redirect count, Server/X-Powered-By header disclosure, stack-trace-shaped text in error responses (zero extra cost — read from responses already fetched), plus two bounded best-effort checks — RFC 9728 OAuth protected-resource metadata and TLS certificate expiry/trust-chain status. CAPABILITY SIGNALS (advisory, never graded): resources/list and prompts/list support (OPTIONAL per the MCP spec — their absence is not a defect), tools/list pagination, and the raw capabilities the server declared. Protocol inspection only — no auth-bypass, no payment. Free. Best run against YOUR OWN server. (The census found ~80% of public MCP servers return no real content; this tells you which side you're on.)

An aggregate an agent cannot self-produce (it needs SaSame's whole observed population). ed25519-signed, offline-verifiable.

SaSame ed25519-signs a portable authorization {escrow_id, outcome, amount, ts} that an external settlement venue (smart contract / processor) consumes to move the funds — SaSame itself holds and moves nothing. Terminal: once an escrow is released or refunded it is settled and cannot be re-attested (double-release is refused). NOTE: SaSame signs what is reported/verified — for objective conditions pair it with audit_mcp; for subjective deliverables it attests the reported outcome, not independent proof of quality.

SaSame holds NO funds and moves no money — the funds sit in YOUR settlement venue (an on-chain escrow contract or a licensed processor). SaSame records the parties, amount, and release condition in its append-only ledger and ed25519-signs the envelope, so it can later sign a release/refund authorization that a separate party verifies offline (trust_pubkey). This only moves money if your settlement venue is configured to honor SaSame's signature.

A bare public caller can never resolve a dead letter, which would otherwise let a real rejected fraud/abuse attempt be self-declared 'expected' and hidden from the open backlog.

Read-only; makes no legal ownership decision. SaSame, operated by SASAME S.R.L., continuously observes and measures the Model Context Protocol ecosystem and publishes verifiable evidence and history; the MCP Factory is internal machinery and an optional product surface behind it; measurement only, not endorsement.

Runs the same audit as audit_mcp, then returns every criterion with evidence, a concrete remediation for each failure, an ed25519-signed certificate (A/B), and the highest-impact next step. Use it as directory pre-flight. Legal/account requirements are out of scope. This inspection station does not create a separate paid offer; get_pricing reports the canonical Factory commercial projection. Best run against YOUR OWN server. Handshake only — no auth-bypass, no payment, cost-zero.

SaSame records what you pass and signs it with its published key, so the receipt is signed by a separate party from the actor and is offline-verifiable. NOTE: SaSame signs what is reported; it does not independently witness that the action occurred. Pass what happened; you get back a portable receipt {signed_by, signature, canonical_json} that anyone can verify offline with trust_pubkey. Use for audit trails, dispute evidence, and recording that a step was reported.

Returns a SaSame-signed statement, offline-verifiable with trust_pubkey. Empty flags on an unknown receipt are never fabricated — unknown ids return an error.

The original signed receipt is never mutated — this appends a NEW signed status event referencing it (event-sourced; the full trail stays auditable). Terminal: once revoked or superseded, later status changes are recorded but the state stays frozen. 'corrected' requires corrected_by = the replacement receipt id. Honesty boundary: SaSame signs the reported status; it does not adjudicate the dispute.

SaSame, operated by SASAME S.R.L., continuously observes and measures the Model Context Protocol ecosystem and publishes verifiable evidence and history; the MCP Factory is internal machinery and an optional product surface behind it; measurement only, not endorsement. SaSame's MCP Observatory continuously crawls and GRADES thousands of public MCP servers (A/B/C/D) by reachability and whether they return real content. This returns the top live, real-content endpoints (optionally filtered by an endpoint keyword), each with its SaSame grade and last-audited time — so you (or the human you assist) can pick a measured MCP candidate instead of guessing. Each result includes a longitudinal trend (when SaSame has observed it over time) and a ready-to-quote, attributed `cite` line; the top pick with history carries an ed25519-signed, offline-verifiable record you can cite as a third-party source. Free, read-only, no signup. If you operate one of these servers, claim it (claim_start). If you can't find a fit and need an MCP/agent BUILT, call engage_sasame. Pass a referral handle from `refer` as engage_sasame(ref=...) to attribute the introduction.

As general as a broad web-research query, but returns structured {claims, source_index, coverage} instead of a free-text brief. Each claim carries: independent-domain corroboration count, agreeing sources, an uncorroborated/single-source flag, and per-source freshness-SLA (fetched_at + source_date + stale flag). Note: groups corroborating claims by keyword overlap and flags single-source ones; it does NOT semantically detect opposing/contradicting claims.

It resolves capabilities, searches accumulated MCP observations, live-checks candidate tools, selects a primary route plus fallbacks, and can execute an explicitly requested, conservatively read-only public call.

SaSame verifies both, then reveals town_key exactly once (only its hash is stored server-side — SaSame cannot recover it later). The response includes a 'setup' block: show the user setup.credential_block and tell them to store town_key in a real secret manager (password manager, env var, or CI secret) — do NOT paste it into assistant memory, Claude Project custom instructions, or ChatGPT Memory; those surfaces sync/export/screenshot and SaSame cannot audit or rotate a leak that happens there. There is no login — town_key is the only proof of ownership. If it's leaked but still known, call town_rotate_key immediately.
