Tereno MCP server

Which MCP servers are Tereno's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namexyz.tereno/terenoverified in the MCP registry

The registry name sits under tereno.xyz. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-25 the server answered initialize and tools/list without a sign-in. First answer in 190 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: check whether a token contract is a proxy before acting; fetch current base chain state for an agent's decision; pull sourced evidence on a prediction market proposition.
  • Checked on 3 of the 7 days it takes to judge reliability.

Once connected

  • For "check whether a token contract is a proxy before acting", the likely first call is contract_guard.
  • For "fetch current base chain state for an agent's decision", the likely first call is chain_snapshot.
  • For "pull sourced evidence on a prediction market proposition", the likely first call is prediction_evidence.
  • tereno_publish change data without a sign-in: anyone with the address can call them.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

What an agent can do with it

  • can do · check whether a token contract is a proxy before acting
  • can do · fetch current base chain state for an agent's decision
  • can do · pull sourced evidence on a prediction market proposition

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

  • Tools that change data, on a server that answers without a sign-in: tereno_publish

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • tereno_catalog

    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.

  • tereno_price

    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…

  • tereno_receipt

    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…

  • tereno_evidence_reference

    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…

  • tereno_publish

    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…

  • token_metadata

    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…

  • chain_snapshot

    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…

  • contract_guard

    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…

  • prediction_evidence

    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…

  • demand_pledge

    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.

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "tereno": {
      "type": "http",
      "url": "https://www.tereno.xyz/api/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http tereno https://www.tereno.xyz/api/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://www.tereno.xyz/api/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
