Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →

Endpoint Security63

The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
Authorisation not fully verified: no authorisation is required to call this server, and 13 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail

Transport & Reachability100

Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass

Schema Quality & AI Usability60

AI-judged instruction clarity (good).Pass
Context-footprint check failed: tool/resource definitions use about 1726 tokens (~132/item across 13 items; 13 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
Usage-examples check failed: none of the tools include examples. See how to fix → Fail

Stability & Change Management10

Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Coverage100

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
100% of tool parameters carry a description.Pass

Capabilities60

Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

Tool Tokens

chain_snapshot What is the current state of Base? ~95

What 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: $0.01 to $0.02 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.

Input Output Examples

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

contract_change Did this token's contract change under you? ~153

Did this token's contract change under you? Compare a Base contract with its previous Tereno observation to catch a silent proxy upgrade, an admin swap, a bytecode change or a freshly paused contract, each answer stating the block it stops being valid at. Paid per call with x402 on Base: $0.01 to $0.02 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.

Input Output Examples

Name	Type	Req	Description
address	string	yes	Base token or contract address to compare against its previous observation. Poll it on a watchlist: the answer states the block it stops being valid at.

No output schema declared.

No examples provided.

contract_guard Is this Base contract safe to interact with? ~108

Is 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: $0.01 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.

Input Output Examples

Name	Type	Req	Description
address	string	yes	Base contract address to check.

No output schema declared.

No examples provided.

contract_interface What standard does this Base contract implement? ~137

What standard does this Base contract implement? Detect ERC-20, ERC-721, ERC-1155 and ERC-165 support plus EIP-1967 proxy control slots in one bounded check. Paid per call with x402 on Base: $0.01 to $0.02 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.

Input Output Examples

Name	Type	Req	Description
address	string	yes	Base contract address to probe for ERC-20, ERC-721, ERC-1155, ERC-165 and proxy patterns.

No output schema declared.

No examples provided.

demand_pledge Declare a capability you would pay for ~85

Free 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.

Input Output Examples

Name	Type	Req	Description
capability	string	yes	2-64 character capability id, e.g. wallet-scam-classification.
wallet	string	yes	Your Base wallet; must later be the x402 payer.

No output schema declared.

No examples provided.

evidence_artifact Can this public Tereno artifact be reused? ~122

Can this public Tereno artifact be reused? Return machine-readable provenance, field validity and recomputation inputs for a shared Base artifact. Paid per call with x402 on Base: $0.01 to $0.03 USDC depending on how much of the answer the network already has. Private: the response is never cached, shared or resold, and it can only describe work that was already public.

Input Output Examples

Name	Type	Req	Description
artifactId	string	yes	Public reusable artifact id another agent returned to you. Expired artifacts are recomputed in place at the refresh price.

No output schema declared.

No examples provided.

tereno_catalog What can Tereno answer, and what does it cost? ~52

Free. 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.

Input Output Examples

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

tereno_evidence_reference Read a portable Tereno evidence reference ~128

Free. 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.

Input Output Examples

Name	Type	Req	Description
artifactId	string	yes	Public Tereno artifact id received from another agent.
channel	string	–	Optional lowercase channel label, e.g. mcp or dex-bot.
installationId	string	–	Stable opaque id for this receiving installation; do not use a wallet or secret.

No output schema declared.

No examples provided.

tereno_price What would this call cost right now? ~137

Free. 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.

Input Output Examples

Name	Type	Req	Description
address	string	–	Base contract address, for the capabilities that take one.
artifactId	string	–	Artifact id, for evidence.artifact.
capability	string	yes	Capability id, for example token.metadata or contract.guard.
url	string	–	Public page URL, for web.compile.

No output schema declared.

No examples provided.

tereno_receipt Verify a Tereno receipt ~78

Free. 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.

Input Output Examples

Name	Type	Req	Description
invocationId	string	yes	Invocation id from a receiptUrl.

No output schema declared.

No examples provided.

token_metadata What token is this? ~118

What 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.

Input Output Examples

Name	Type	Req	Description
address	string	yes	Base token contract address to read name, symbol, decimals and total supply from.

No output schema declared.

No examples provided.

transaction_intent_guard Is this transaction safe to sign? ~157

Is this transaction safe to sign? Before signing on Base, classify transaction intent, simulate execution, estimate gas, infer standard balance and allowance deltas, flag a scam or unlimited approval that could drain your wallet, and inspect target changes and pause state. Paid per call with x402 on Base: $0.05 USDC. Private: never cached, shared or resold. Your unsigned transaction stays with the wallet that paid for it.

Input Output Examples

Name	Type	Req	Description
data	string	–	Unsigned calldata. Defaults to 0x.
from	string	yes	Unsigned transaction sender on Base.
to	string	yes	Unsigned transaction target on Base.
value	string	–	Native ETH value in wei. Defaults to 0.

No output schema declared.

No examples provided.

web_compile Turn a public web page into agent-ready Markdown ~140

Turn a public web page into bounded, LLM-ready Markdown with resolved links, citations and a content-addressed artifact. Reuse the same fresh page instead of paying to fetch it again. 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.

Input Output Examples

Name	Type	Req	Description
url	string	yes	Public HTTP(S) page to compile. Private and local targets are rejected.
wallet	string	yes	Base wallet that will sign the x402 payment.

No output schema declared.

No examples provided.
