Available components
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 → Why this is hard to score →
Endpoint Security66
- 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 10 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 is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability74
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1473 tokens (~147/item across 10 items; 10 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 Management59
- Stability check failed: schema churn in the 30 days we've observed: 6 tool removals, 0 breaking changes, 0 auth/transport breaks, 1 additions. See how to fix → Fail
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
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "tereno_publish" implies "publish" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail
How do I install the Tereno on Base MCP server?
Tereno on Base is a hosted endpoint at https://www.tereno.xyz/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
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: $0.002 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.
Input schema present but exposes no named parameters.
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: $0.02 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.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | Base contract address to check. |
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.
| 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.
prediction_evidence Gather sourced machine-readable evidence supporting or contradicting a prediction market proposition ~146
Returns 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.
| Name | Type | Req | Description |
|---|---|---|---|
| context | object | – | Optional contextual metadata. |
| market | string | – | Market venue identifier (e.g. polymarket, omen, kalshi). Defaults to polymarket. |
| marketUrl | string | – | Optional market URL for resolution rules extraction. |
| question | string | yes | Prediction market question or proposition. |
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 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.
| 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? ~126
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.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | – | Base contract address, for the capabilities that take one. |
| capability | string | yes | Capability id: token.metadata, chain.snapshot, contract.guard or prediction.evidence. |
| question | string | – | Proposition, for prediction.evidence. |
No output schema declared.
No examples provided.
tereno_publish Publish work you already computed, and get it attested on-chain ~372
Free, 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.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | Base contract address the fingerprint is for. |
| agentId | string | – | Optional ERC-8004 agentId you own, as a decimal string. Ownership is verified against ownerOf before anything is written on-chain; an unverifiable claim is skipped and changes nothing about the publi… |
| bytecodeBytes | number | – | Length of the deployed bytecode in bytes. Must be 0 exactly when bytecodeHash is omitted. |
| bytecodeHash | string | – | keccak256 of the deployed bytecode you read. Omit only for an address with no code. |
| computedAtBlock | number | yes | Block number you read the bytecode at. |
| registerIfMissing | boolean | – | Explicit consent to be attested via a Tereno-delegated identity you already paid POST /api/v1/agents/register for. Bind it by signing <contract-address>:erc8004-register as the resource. Does not its… |
| wallet | string | yes | Your Base wallet. Becomes the seeder and earns the reuse dividend. |
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.
| 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.
| 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.
