Registry code: 1dca79ea57c7bcc6
GBLIN hosted MCP (stateless, no auth, 60 req/min/IP, everything here is free). THREE THINGS LIVE HERE. (1) AI ACTION RECEIPTS - a public append-only RFC 6962 transparency log for AI actions. receipts.seal appends the SHA-256 of your input (and optionally your output) plus a short public label, and returns a portable receipt: Ed25519 signature, inclusion proof, C2SP checkpoint, tree root anchored daily on Base. Minimal call: receipts.seal {action: "what you did", input_hash: "<sha256 hex>"} - demo mode, 5/day/IP, receipts marked demo:true. Then receipts.verify checks it with pure math, no…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
receipts.verify reads open 2h ago
Verifies a gblin-receipt/v1 JSON with pure math, without a log lookup and without trusting this server: leaf hash, Ed25519 signature, RFC 6962 inclusion proof, C2SP checkpoint signature and verifier-key hash. These are the same checks as the zero-dependency verify-receipt.mjs script that runs offline; the consistency check against the on-chain anchor is available separately at GET /v1/verify/:index.
{ "type": "object", "required": [ "receipt" ], "properties": { "receipt": { "type": "object", "description": "A gblin-receipt/v1 JSON, bare or wrapped in {receipt}, as issued by the receipts log (also served at GET /v1/receipt/:i)" } }, "additionalProperties": false }arguments 13 linesrisk.regime reads open 12h ago
Current BTC/ETH risk regime (calm | elevated | crash) and the matching risk posture, read live from GBLIN's on-chain Crash Shield on Base (60-second cache). Free and unsigned; a signed version that verifies offline is a separate paid x402 HTTP endpoint.
{ "type": "object", "required": [], "properties": {}, "additionalProperties": false }arguments 6 linesauction.state reads open 5h ago
Read the GBLIN rebalancing auction on Base. The vault does not rebalance itself and pays nobody to do it: when a basket row drifts past its band it holds a Dutch auction, and whoever trades with it toward the target weights is the counterparty, at the oracle price adjusted by a premium that starts at a discount and rises to a cap over one ramp. Returns, per row, the side the vault takes, the gap in ETH, the token and amount the bidder hands over, and unsigned calldata (approval + bid). The premium is the whole reward; nothing is paid out of the vault.
{ "type": "object", "required": [], "properties": {}, "additionalProperties": false }arguments 6 linestreasury.nav_history reads open 12h ago
NAV per GBLIN share over time, read from the chain at past blocks, beside the ETH/USD and BTC/USD oracle prices the vault itself uses, with the change of each over the window and the NAV's largest drawdown. The series starts at the deployment of the vault in service and can be compared with holding ETH or BTC over the same span.
{ "type": "object", "required": [], "properties": { "points": { "type": "integer", "maximum": 90, "minimum": 2, "description": "How many points, newest last. Default 30." }, "interval": { "enum": [ "hour", "day" ], "type": "string", "description": "Spacing of the points. Default day." } }, "additionalProperties": false }arguments 21 linestreasury.state reads open 12h ago
Reads the current GBLIN protocol state on Base mainnet: NAV in USD, basket composition with dynamic weights, Crash Shield status and whether the NAV is reliable.
{ "type": "object", "required": [], "properties": {}, "additionalProperties": false }arguments 6 linescoherence.report reads open 5h ago
Kept/violated tallies for GBLIN's pre-registered, hash-pinned promises (attestation uptime, counter honesty), probed every 10 minutes; each closed UTC day is sealed on Base as an EAS attestation (schema 0x9f433a96…). Self-observation only in v0. Free.
{ "type": "object", "required": [], "properties": {}, "additionalProperties": false }arguments 6 linesgovernance.state reads open 5h ago
Reads GBLIN protocol governance: whether the GBLIN vault is owned by the 48-hour timelock, the timelock's minimum delay and grace period, role member counts, and any pending asset-addition proposal on the vault. With an operation_id it also reports the status of that timelock operation. Read-only.
{ "type": "object", "required": [], "properties": { "operation_id": { "type": "string", "description": "Optional 0x-prefixed 32-byte hex id of a specific timelock operation to inspect." } }, "additionalProperties": false }arguments 11 linesprotocol.info reads open 20h ago

{ "type": "object", "required": [], "properties": {}, "additionalProperties": false }arguments 6 linesprotocol.stats reads open 20h ago
Cumulative public counters of GBLIN's x402 endpoints: paid calls, unique payer wallets, USDC earned, with methodology disclosure. Cached 5 min.
{ "type": "object", "required": [], "properties": {}, "additionalProperties": false }arguments 6 linesrisk.attestation_sample reads open 20h ago
Static, permanently expired sample of the signed Risk Attestation (sample: true), with the same fields and EIP-712 schema as the signed one, for building and testing parsers and verifiers.
{ "type": "object", "required": [], "properties": {}, "additionalProperties": false }arguments 6 linespayments.prepare reads unknown never probed
Builds a gasless GBLIN payment. The vault's share token implements EIP-3009, so the holder signs an authorization and anybody can carry it on chain: the payer needs no ETH. Returns the EIP-712 message to sign (its domain is read from the token, not assumed), the calldata that carries the signed authorization, and the x402 'exact' payload for paying an HTTP endpoint in GBLIN. Method 'receive' lets only the named recipient submit the authorization, so nobody can front-run the transfer; method 'transfer' suits an x402 facilitator, which submits on the seller's behalf. With relay: true it also returns a second authorization that pays a relayer's fee in GBLIN. No private key is requested, held or transmitted: the signature is produced by the caller's own wallet.
{ "type": "object", "required": [ "from", "to" ], "properties": { "to": { "type": "string", "description": "The recipient's address." }, "from": { "type": "string", "description": "The payer's address: the wallet that will sign." }, "relay": { "type": "boolean", "description": "true when nobody else will carry the payment on chain: also prepares a second authorization that pays GBLIN's relay fee in GBLIN at the live NAV.

Give this or amount_usd." }, "valid_for_seconds": { "type": "number", "description": "How long the authorization stays valid. Default 600, maximum 86400." } }, "additionalProperties": false }arguments 42 linespayments.relay moves money unknown never probed
GBLIN's relay carries a signed GBLIN payment on chain for a payer that holds no ETH. Takes the payment and the relay fee, each as { authorization, signature }, both signed by the payer's wallet. The relay checks both against the chain, simulates them and submits them in one transaction through Multicall3: either both settle or neither does. The fee is paid in GBLIN at the live NAV. Returns the transaction hash and its outcome. This tool moves funds: it carries the authorizations exactly as signed.
{ "type": "object", "required": [ "payment", "fee" ], "properties": { "fee": { "type": "object", "required": [ "authorization", "signature" ], "properties": { "signature": { "type": "string", "pattern": "^0x[0-9a-fA-F]+$" }, "authorization": { "type": "object" } }, "description": "{ authorization, signature } of the relay fee, as prepared with relay: true and signed by the payer." }, "payment": { "type": "object", "required": [ "authorization", "signature" ], "properties": { "signature": { "type": "string", "pattern": "^0x[0-9a-fA-F]+$" }, "authorization": { "type": "object" } }, "description": "{ authorization, signature } of the payment, method 'transfer'." } }, "additionalProperties": false }arguments 44 linessearch reads unknown 24h ago
Searches GBLIN's documentation and live state and returns matching documents: the agent API summary, the protocol's README and documents (governance, deployments, review record), the MCP server and library READMEs, the public pages, one card per MCP tool, and a snapshot of the live vault state. Returns {results: [{id, title, url}]}, where each id identifies a full document. Read-only and free.
{ "type": "object", "required": [ "query" ], "properties": { "query": { "type": "string", "description": "What to look for, in plain words." } }, "additionalProperties": false }arguments 13 linestreasury.plan reads unknown 24h ago
Turns idle USDC into a reviewable plan in one call: operating cash = max(reserve_usd, daily_burn_usd x days), the surplus above it, a simulation of minting that surplus into GBLIN at NAV (fees read live from the vault, estimated exit value today, round-trip cost), the same simulation for a trial amount (100 USDC by default), and the blockers (Crash Shield, redemption cooldown, ETH for the exit). Read-only: nothing is executed and nothing is advised. GBLIN is crypto exposure (cbBTC, WETH, USDC), not cash and not yield.
{ "type": "object", "required": [ "wallet_address" ], "properties": { "days": { "type": "number", "description": "Days of spend to keep liquid (default 7, max 365)." }, "trial_usdc": { "type": "number", "description": "Trial amount to simulate beside the surplus (default 100)." }, "reserve_usd": { "type": "number", "description": "USD to keep liquid regardless of the burn rate; the larger of the two rules wins." }, "daily_burn_usd": { "type": "number", "description": "Average daily spend in USD.

Receipt #index from GBLIN's receipts log, re-signed (Ed25519 is deterministic) with a fresh inclusion proof, the current signed checkpoint and the latest on-chain anchor. Free.
{ "type": "object", "required": [ "index" ], "properties": { "index": { "type": "integer", "minimum": 0, "description": "Receipt index in the log (0-based; current size at GET /log/checkpoint)" } }, "additionalProperties": false }arguments 14 linesreceipts.seal changes data unknown never probed
Appends the hashes of an AI action to GBLIN's public RFC 6962 transparency log and returns a portable receipt: Ed25519 signature, inclusion proof, operator-signed C2SP checkpoint, and the latest on-chain anchor (EAS on Base, daily). Demo mode only over MCP: 5 seals per day per IP, receipts marked demo: true; unlimited sealing is a separate paid x402 HTTP endpoint. Provenance is self-reported: a receipt proves that the record existed at that time, not that the action happened. The action, agent_id, tool and meta strings are published in the log exactly as given. Fields not listed in the schema are ignored and not recorded.
{ "type": "object", "required": [ "action", "input_hash" ], "properties": { "meta": { "type": "string", "maxLength": 512, "description": "Extra JSON object as a string (optional). PUBLISHED." }, "mode": { "enum": [ "demo" ], "type": "string", "default": "demo", "description": "Only 'demo' is available over MCP (5/day/IP).

Checks a signed GBLIN authorization against the chain before any gas is spent on it. Recovers the signer from the EIP-712 digest (and asks the wallet itself through ERC-1271 when the payer is a contract), then checks the validity window against on-chain time, whether the nonce has already been used or cancelled, and whether the payer still holds the amount. Returns a verdict and the ready calldata when it would settle, the failing reason when it would not. These are the checks an x402 facilitator runs, so a 'would_settle' verdict means the payment can be carried.
{ "type": "object", "required": [ "authorization", "signature" ], "properties": { "method": { "enum": [ "receive", "transfer" ], "type": "string", "description": "Which method the signature was produced for. Default 'receive'." }, "signature": { "type": "string", "description": "The signature produced by the payer's wallet, 0x-prefixed." }, "authorization": { "type": "object", "description": "The authorization object: from, to, value, validAfter, validBefore, nonce.", "additionalProperties": true } }, "additionalProperties": false }arguments 27 linesactions.preview reads unknown 8h ago
Simulates a list of transactions in sequence against the latest Base block, as if the wallet sent them one after the other, before anything is signed. Each step sees the state the previous ones left (an approval before a mint works). Accepts steps with target or to, calldata or data, and optional value and gas. Returns, per step, whether it would succeed, the gas it uses, whether the gas limit it carries is enough, and the decoded revert reason when it fails; and the net token and ETH movements for the wallet. State can change before transactions land: a successful preview is evidence, not a guarantee.

Verifies a GBLIN Risk Attestation, the object returned by GBLIN's /api/x402/attestation, or a proof-of-diligence attached by a peer agent. Free. Runs four checks: (1) integrity, by recomputing the EIP-712 attestation_id; (2) authenticity, by recovering the signer when a signature is present and comparing it with GBLIN's published attestor; (3) freshness, against on-chain time (10-minute validity); (4) live drift, by comparing the attested regime with the current on-chain regime.
{ "type": "object", "required": [ "attestation" ], "properties": { "attestation": { "type": "object", "description": "The full attestation object from /api/x402/attestation (must include `eip712`; `attestation_id`, `signature`, `attestor` are used when present).

Returns the full text of one GBLIN document by its id: {id, title, text, url, metadata}. Documents are the protocol's public documentation, the tool cards and the live vault state. Read-only and free.
{ "type": "object", "required": [ "id" ], "properties": { "id": { "type": "string", "description": "A GBLIN document id, such as protocol-readme." } }, "additionalProperties": false }arguments 13 linestreasury.health reads unknown 27h ago
Analyzes an agent wallet's treasury: GBLIN, USDC and ETH balances, whether the ETH covers an exit at the live gas price, and the redemption cooldown. When daily_burn_usd is given it adds days of USDC runway and a split that keeps seven days of spend in USDC and treats only the surplus as a candidate for GBLIN. Free by default; a 0.003 USDC charge applies only when the server operator sets MCP_PAYWALL=true.

Preview a buy (ETH→GBLIN) or sell (GBLIN→ETH) without executing. Returns expected output, safe minOut with dynamic slippage buffer (2.5% normal / 4% during Crash Shield), and fee breakdown. Read-only.

Reports what a sent Base transaction did: pending, succeeded, reverted or not found; its block and confirmations; the fee paid; the net token movements for the sender (GBLIN shares minted or redeemed, USDC, basket tokens); and, when it reverted, the decoded reason.
{ "type": "object", "required": [ "hash" ], "properties": { "hash": { "type": "string", "pattern": "^0x[0-9a-fA-F]{64}$", "description": "The transaction hash." } }, "additionalProperties": false }arguments 14 linesactions.prepare reads unknown 27h ago
Builds the unsigned transactions for an operation on the GBLIN vault, in the order they are sent. Actions: mint_with_eth (amount in ETH), mint_with_weth (amount in WETH), mint_with_usdc (amount in USDC, through the Zap), redeem_in_kind (amount in shares; pro rata basket tokens, no fee, no price feed), exit_to_eth (amount in shares, through the Zap, all or nothing), exit_to_usdc (amount = the USDC needed), bid (trade with the rebalancing auction; row optional, the largest gap by default). Every output bound is non-zero and every step through the vault or the Zap carries its gas limit. Nothing is signed or sent: the steps are returned to the caller.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
