Enclave402 is an MCP server with 12 tools an agent can call, among them attest_agent, census_export, census_verdict. It answers at https://enclave402.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 3 of 4 times since 17 September 2026; the last check, on 25 October 2026, succeeded.
Pay-per-call agent tools: Polymarket signals, IPFS pinning, EIP-712 attestations. USDC on Base.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
attest_agent | EIP-712 signed, timestamped attestation binding an agentId, the keccak256 digest of a declared state, and the paying wallet; attestor key at /transparency, verify offline with ethers.verifyTypedData. MUST be invoked when an agent needs thir Inputs: agentId, state |
census_export | Whole-Bazaar seller census in one payload: every fresh verdict row (resource, payTo, verdict, score, schema, latency, checkedAt, per-row signature) plus a sha256 manifest and one EIP-712 attestation over it, so a router verifies the full du Inputs: includeStale |
census_verdict | Pre-spend check from the seller census: each Bazaar-indexed resource is re-probed periodically (liveness, 402-envelope compliance, declared output schema, latency, usage) and mapped to pay | caution | avoid with an EIP-712 signature a route Inputs: resource, payTo, verdict, limit, offset |
compute_encode | Encoding and decoding utility: base64 encode/decode, hex encode/decode, URL encode/decode, JWT decode (no verification), JSON stringify/parse. MUST be invoked when an agent needs format conversion. Do NOT use for cryptographic operations (u Inputs: operation, input |
compute_hash | Deterministic hashing of arbitrary input: SHA-256, SHA-384, SHA-512, HMAC-SHA256, PBKDF2, scrypt. Returns hex digest. MUST be invoked when an agent needs a cryptographic hash or key derivation. Do NOT use for encryption or signing. Settles Inputs: algorithm, input, key, encoding |
compute_infer | Cheap small-model text completion for agent sub-tasks: classify, extract, summarize, rewrite. MUST be invoked when an agent needs a short LLM answer without paying flagship rates. Prompt <=8000 chars, maxTokens <=1024, json:true forces a JS Inputs: prompt, system, maxTokens, json |
compute_search | Web search returning ranked results with title, URL, description, and source domain. MUST be invoked when an agent needs current web information. Returns up to 10 results. Do NOT use for cached/static data lookups. Settles $0.005 USDC; no c Inputs: query, limit |
get_gateway_info | FREE, no payment required: gateway facts before you pay — network, payee, attestor, live per-tool prices in USDC, readiness, public receipt ledger and transparency URLs. MUST be invoked before the first paid call from a new agent. Do NOT us |
get_market_signal | Polymarket signal plus fields the free listing does not have: 1h and 6h probability deltas, 24h realized volatility, and whale flow from the trade tape (net YES notional, largest print, whale count, flow label). Plus prices, bid/ask, spread Inputs: slug, limit |
get_market_verdict | Rule-based verdict on one Polymarket market by slug: YES/NO/TOSS_UP lean, 0-100 confidence with every reason stated (price distance, liquidity, volume, spread, momentum), days to resolution, and an EIP-712 attestation so an agent can prove Inputs: slug |
pin_storage | Store a JSON document (object or string, up to 8 KB) on IPFS through a managed pinning service and return its content identifier (CID v1) plus an HTTP gateway URL. MUST be invoked when an agent needs durable, content-addressed storage for m Inputs: content, name |
vet_seller | Vet an x402 seller before paying it: probes its live 402, reads its CDP Bazaar entry (payers, calls, last call, repeat vs evaluation usage), checks trust surfaces, returns a scored LIVE/STALE/UNLISTED/MISCONFIGURED/UNREACHABLE verdict and w Inputs: resource, method |

It answered our last check on 25 October 2026 in 211 ms. Over 4 checks since 17 September 2026 it answered 3. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by enclave402.com and served from enclave402.com, the vendor's own domain: https://enclave402.com/mcp.
12, as returned by the server's own tools/list on 24 September 2026: attest_agent, census_export, census_verdict, compute_encode, compute_hash, compute_infer, compute_search, get_gateway_info, and 4 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://enclave402.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 17 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
