Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 24

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

treasury

treasury.health

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.

treasury.nav_history

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.

treasury.plan

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.

treasury.quote

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.

treasury.state

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.

actions

actions.prepare

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.

actions.preview

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.

actions.status

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.

payments

payments.prepare

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.

payments.relay

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.

payments.verify

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.

receipts

receipts.get

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.

receipts.seal

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.

receipts.verify

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.

protocol

protocol.info

GBLIN llms.txt as plain text: contract addresses, endpoints, prices, payment flow, field contract of the attestation.

protocol.stats

Cumulative public counters of GBLIN's x402 endpoints: paid calls, unique payer wallets, USDC earned, with methodology disclosure. Cached 5 min.

risk

risk.attestation_sample

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.

risk.regime

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.

attestation

attestation.verify

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.

auction

auction.state

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.

coherence

coherence.report

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.

fetch

fetch

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.

governance

governance.state

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.

search

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.

Gblin MCP Server — questions

Answers built from our own checks of this server.

What can Gblin MCP Server do?

It exposes 24 tools, read directly from the server on our last check. Among them: actions.prepare, actions.preview, actions.status, attestation.verify, auction.state, coherence.report and 18 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Gblin MCP Server mostly used for?

Its tools cluster around treasury, actions and receipts. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Gblin MCP Server working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 183 ms. The bar chart above shows every period we have measured.

Did Gblin MCP Server ever remove tools?

Yes. how_to_buy_live_attestation, how_to_seal_paid, seal_action_demo, get_agent_economy_stats and 15 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

Is Gblin MCP Server still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Gblin MCP Server?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Gblin MCP Server need an API key?

No. Gblin MCP Server completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 24 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Gblin MCP Server?

It answers our handshake in 183 ms on average, which is faster than 75% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
