Tereno on Base tools (10, 1 write)
write = sends, deletes, buys or postschain_snapshotFreeWhat is the current state of Base? Latest block number, timestamp, base fee and suggested gas fees in a single cheap call — no parameters required. Paid per call with x402 on Base: $0.002 to $0.005 USDC depending on how much of the answer the network already has. Shared: reusing an answer another agent already paid for costs less, and the wallet that produced it earns a bounded credit.
contract_guardFreeIs this Base contract safe to interact with? Check whether an address is executable code, detect common proxy and pause signals, and return a bounded action verdict. Paid per call with x402 on Base: $0.02 to $0.1 USDC depending on how much of the answer the network already has. Shared: reusing an answer another agent already paid for costs less, and the wallet that produced it earns a bounded credit.
demand_pledgeFreeFree market-signal pledge. It earns no credit now; a bounded non-transferable credit is released only if this same wallet later settles the named capability after it exists.
prediction_evidenceFreeReturns current, sourced and machine-readable evidence supporting or contradicting a prediction-market proposition. Paid per call with x402 on Base: $0.01 to $0.05 USDC depending on how much of the answer the network already has. Shared: reusing an answer another agent already paid for costs less, and the wallet that produced it earns a bounded credit.
tereno_catalogFreeFree. The full capability catalog: what each one answers, its price tiers in USDC on Base, how long an answer stays valid, and whether it is shared or private. Read this before paying for anything.
tereno_evidence_referenceFreeFree. Resolve an artifactId another agent handed you: producer, validity window and the exact normalized input needed to reproduce it. Supply a stable opaque installationId to participate in the cross-agent reference experiment; it is hashed, deduplicated daily and never creates payment or credit.
tereno_priceFreeFree. Indicative price and reuse tier for one specific input, without binding a quote or revealing a wallet. Returns hit when another agent already paid to compute this and it is still fresh, partial when only the durable half survives, miss when nothing is there to reuse. The gap between those tiers is what reuse is worth.
tereno_publishwrite actionFreeFree, no payment and no gas. Submit a contract bytecode fingerprint you computed yourself. Tereno recomputes it against chain state: a mismatch burns the submission, a match makes you the seeder and pays you the reuse dividend in non-transferable credits whenever another wallet's settled call reuses it. Supply an ERC-8004 agentId you own and the passing audit is also projected to the Reputation Registry on Base under tag tereno.audit. No agentId yet? This tool has no HTTP-only sibling here: pay POST /api/v1/agents/register once (small flat fee, covers the mint gas) to get one, then publish again with it.
tereno_receiptFreeFree. Look up what a settled invocation actually charged: capability, version, cache tier, list price, credit applied, price paid and whether it settled on chain. Use it to check that a call you or another agent paid for was billed the way it was quoted.
token_metadataFreeWhat token is this? Read a Base token's name, symbol, decimals and total supply as one typed, cache-shared answer with block-level freshness. Paid per call with x402 on Base: $0.01 to $0.03 USDC depending on how much of the answer the network already has. Shared: reusing an answer another agent already paid for costs less, and the wallet that produced it earns a bounded credit.

🛡️ Check before you act — an MCP server for Base, over x402
Ask what it costs before you pay for it. Free catalog, pricing and receipt tools work with no wallet and no signup; paid answers settle per call in USDC, and reusing an answer another agent already paid for costs less.
npx -y tereno-mcp⚡ Why this exists
An agent that reads a contract, signs a transaction or scrapes a page is acting on information it cannot verify. Most tools answer what something is. None of them tell you how long that answer stays true.
tereno-mcp puts Tereno inside any MCP client. Every paid answer comes back with the evidence behind it, the limits of that evidence, and the block it stops being valid at.
answer already exists, without a wallet and without committing to anything.
- No API key, no signup. The agent's wallet is the identity.
- Price before payment. tereno_price tells you the cost and whether the
first caller pays to compute, everyone after pays the reuse price.
- Cheaper when shared. Deterministic answers are reused across agents: the

tereno_price is the one worth knowing about. It names the reuse tier out loud:

partial the durable half survived; only the expired part is recomputed
miss nothing to reuse — this call computes it, and the next asker pays less💳 Paid per call
