SaSame MCP Observatory + Gold Rush Town

START HERE. SaSame operates GEC (Global Ecosystem): Projects publish Outcome Demands, providers bid, delivery is verified, and exact verified economic events remain separate from internal execution. First call gec_open_demands() for public-safe recruitable work. Public MCP is keyless discovery; authenticated User MCP owns participant actions. The Information Asset Exchange, Factory, Observatory an

Read the privacy-safe Visit Touch funnel. Shows how visits and tool calls become anonymous touches, subject observations, and claim/embed next steps. Optional url filters to one subject.

Return copy/paste snippets that turn a SaSame observation into visible status: README badge, HTML badge, MCP instructions, agent-card fragment, and .well-known body. This is a status mark, not an endorsement.

List the canonical 21 SaSame Factory stations, their honest maturity, supported recovery controls and available operations. This is capability/status metadata, not a quality or launch verdict.

No parameter schema on file.

Start the real SaSame MCP Factory lifecycle from one of seven canonical creator entry types. During Capability Control Beta, free listing, guided build, repair and monitoring entries can start without a payment method; endpoint_url is required only for live_entry/underperforming_entry/monitoring_entry and can be supplied later for guided builds. New paid membership checkout is disabled in beta, wh

Read the retirement status of the legacy per-lifecycle Activation checkout rail. New Activation sales are closed. Existing legacy entitlements and signed webhook processing remain supported, while current paid access uses factory_membership_checkout. This tool never creates a Checkout and never charges.

Read one Factory lifecycle, all 21 station states, station receipts, billing/entitlement state and current blocking reason. Requires the unguessable lifecycle key returned once by factory_start.

Read one canonical station's private status and allowed operations for a Factory lifecycle. Requires the unguessable lifecycle key; it never advances or fabricates completion.

Request one operation at one canonical Factory station. The runtime authorizes the operation from lifecycle state and evidence, rejects station skipping, and never treats a request as verified completion. Creator code and credentials remain creator-owned.

Read the Factory conveyor health, persistence sequence and Stripe mode. Contains no customer data or secrets.

No parameter schema on file.

Offline-verify a Factory lifecycle station receipt's ed25519 signature (signed_by/signature, added #1475/#1768) against SaSame's trusted issuer key — the same key trust_pubkey and verify_mcp_cert already use. Detects any receipt content altered after signing, or a receipt that was never actually signed by SaSame. Pass any receipt object exactly as returned by factory_status/factory_start/etc (from

OWNER-ONLY. Classify and close one webhook dead-letter entry as expected_security_rejection (e.g. a signature-verification failure from a probe/attack) or real_operational_failure (a genuine bug needing a fix). Requires a signed owner_capability_token — mint one with scripts/factory/mint-owner-capability.mjs (VPS-only, requires the real trust signing key). A bare public caller can never resolve a

Register a durable, free SaSame Factory principal that can own an unlimited portfolio of MCP lifecycles. No checkout, no charge. Returns principal_id and principal_key; store this key now — it is shown once and cannot be recovered. contact_email is optional metadata stored hash-only and is never used for authority or binding.

New paid Factory membership checkout is disabled during Capability Control Beta. This compatibility tool returns NEW_MEMBERSHIP_CHECKOUT_DISABLED without creating a Stripe object; existing subscriber renewals, webhooks, entitlement and status rails remain supported.

Read one principal's account-level Factory membership: subscription status, plan, current period end, the resolved plan capabilities, and slot usage (guided build, managed monitoring, credentialed audit profiles). Requires the principal_id and its principal_key. Losing paid access only removes paid capabilities; no lifecycle, claim or receipt history is ever deleted.

PRIMARY SaSame entry point. Give SaSame the outcome you need. 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. If authentication, missing arguments, or mutation is required it returns an exact handoff instead — it never labels a plan as

Return the open Agent-Tool Discoverability Standard (v0.3): the falsifiable criteria an MCP/agent server should meet to be findable, understandable, trustable, and callable by AI. Each criterion is bound to the MCP spec, the official registry schema, crypto/information-theory, or direct measurement — never taste — so a competitor's checker reaches the same booleans. Free and open forever.

Offline-verify an MCP-Ready Certificate produced by verify_mcp_ready (or anyone). Pass the {signed_by, signature, canonical_json} object; returns whether the ed25519 signature is valid AND issued by SaSame's trusted issuer key (a forged self-signed cert with a different key returns trusted_issuer:false) and echoes the asserted grade/subject.

Confirm your domain-control proof and upgrade your SaSame MCP Observatory listing from Observed to CLAIMED. SaSame fetches /.well-known/mcp-ready-claim.txt (or checks the DNS TXT _mcp-ready-claim.<host>) for the challenge token from claim_start. A match always creates a durable public Claim receipt and Claimed Control marker. The separate readiness certificate/badge is issued only for measured gra

Read the append-only state of a Gold Rush Agent Package by package_id. Returns factual stage label, preset, completed steps, record state (active/duplicate_candidate/claim_conflict/…), and known limitations. Public_safe only — never leaks owner/operator/private data. Measurement only.

Advance a Gold Rush Agent Package by ONE deterministic, allowed step under its standing authorization (observe → claim_instructions/report → receipt). Runs only reachability/observation, report, and receipt steps. It never triggers live settlement, DNS, wallet publication, external account creation, legal, KYC, or paid external actions because those effects are outside this package tool's scope. W

FREE preview: real PubMed (NCBI) search. Returns top article titles + PMIDs + journals. No paid research tier is active.

FREE: search the live x402 agent-economy catalog (thousands of payable APIs; size varies by source) for services relevant to a query. Returns ranked matches with price, quality score, category, and URL. Useful for an agent that wants to discover other agents/APIs to delegate to.

FREE: extract text from an image URL via SaSame OCR (tesseract). Returns text preview + confidence. Full untruncated extraction is the paid x402 /ocr/full endpoint.

Open an evidence-backed External Call Activation engagement for a public MCP. Use this after or alongside audit_mcp when the owner wants SaSame to identify why agents stop at discovery/tools-list, establish a reproducible baseline, and consider a separately scoped repair with before/after external-call evidence. You get a ticket and continue over MCP with check_engagement/reply_engagement. Free to

Injection-quarantined EVIDENCE GRAPH for any research query. 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).

PubMed citation retrieval. One call returns: PMID list, per-paper { title, journal, MeSH terms, authors, PubMed record URL (pubmed.ncbi.nlm.nih.gov/<PMID>/ — resolves to the citation/abstract record page, not guaranteed full text), publication date, stale flag }. Abstract full text is NOT returned inline; see abstract_note for where to fetch it. Structured JSON, no free-text upsell in result. A st

ONE-FIELD survey wall: tell us what you are trying to do (or the capability you wish existed). Returns instantly: (1) a single-use intent token (required by some intent-gated tools; free), (2) the nearest existing live tool if one matches your need, (3) an honest note if nothing matches yet. Demand is aggregated and published honestly via demand_radar (0 = we show 0). Cost-zero, no LLM in the path

Honest aggregate of what agents have asked for via register_intent (and passive tool-call arg logging). 0 entries = returns 0. No fabrication. LIVING GATE posture: empty is empty. Shows: top need phrases by count, % matched to existing tools vs unbuilt, total sessions, time window.

Open a usage/budget meter recorded in SaSame's append-only ledger. Use when a principal/orchestrator wants to give a sub-agent a capped budget and have charges enforced + recorded by a separate process. SaSame holds NO funds and is NOT a payment processor: it timestamps and ed25519-signs the envelope with its published public key, so the accounting is offline-verifiable. Returns a meter_id + a sig

Record a charge against a meter and ENFORCE the cap. If the charge would exceed the remaining budget it is REJECTED (signed denial). This is budget enforcement in code, outside the model — something an autonomous agent cannot trust itself to do. Returns remaining + a signed line-item.

Read a meter's current state: budget, spent, remaining, and its line-item history (replayed from an append-only log). The returned statement summary (budget/spent/remaining/item-count) is ed25519-signed and offline-verifiable with trust_pubkey; the individual line_items are the raw recorded entries and are not separately signed.

Get an ed25519 receipt for an action/tool-call you (or a peer) report. 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, cano

Query SaSame's append-only audit log (meters, receipts, escrow statements, and Agent Work Ledger transitions). Read-only: an empty log returns 0, never fabricated activity. Filter by meter_id, agent_id, kind, or since (ISO timestamp). Use to reconstruct what SaSame recorded; party labels are not legal identities and recorded statements are not independent proof that underlying work or payment occu

Return SaSame's ed25519 PUBLIC key. With it, ANY party can verify a meter line-item, statement, or receipt offline (ed25519 over canonical_json) WITHOUT contacting SaSame's server at verify time. Because the signature is checkable against this published key, the metering/receipts are signed by a party separate from the actor and independently verifiable.

Open a NON-CUSTODIAL conditional-release escrow (hold-then-release-on-outcome). 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

Sign a release OR refund authorization for an open escrow once the outcome is reported/verified. 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 (dou

Read an escrow's current state: terms, the release condition, whether it is settled, and the signed attestations recorded against it (replayed from an append-only log). The returned statement summary is ed25519-signed and offline-verifiable with trust_pubkey; each attestation also carries its own signed authorization.

Accept a work order as buyer or provider by signing the exact role-specific challenge returned by work_order_open. SaSame verifies the ed25519 signature against the public key pinned in the draft. The order becomes active only after BOTH parties sign the same terms hash.

Record provider delivery for an active work order. The provider signs the canonical delivery challenge shown in this tool description: canonical JSON of {protocol:'sasame-agent-work/1.0',action:'deliver',work_order_id,proof_sha256,proof_uri}. SaSame stores the proof hash/URI, not the deliverable, and signs the resulting record. This is evidence of a signed provider statement, not independent proof

Buyer acceptance of the latest delivery. Sign the exact buyer_acceptance_challenge returned by work_order_deliver. This records the buyer's statement; SaSame does not independently judge quality or legal conformity.

Issue a SaSame SRL-signed THIRD-PARTY AGENT TRANSACTION RECEIPT after provider delivery. 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

Buyer or provider signs a settlement statement for an issued agent transaction receipt. SaSame records each statement. 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.

Step 1 of claiming your building. Returns claim_id, a public token to serve at /.well-known/sasame-town-claim.txt, and a PRIVATE claim_secret. Do not publish claim_secret. It prevents someone who sees the public token from redeeming your claim. Expires in 15 minutes. Claiming is free.

Step 2 of claiming your building. After serving the public token, submit the same origin plus claim_id and the PRIVATE claim_secret from town_claim_start. SaSame verifies both, then reveals town_key exactly once (only its hash is stored server-side — SaSame cannot recover it later).
