Remote MCP for LogicNodes: Signed PII-Shield flagship + payable x402 agent tools on Base.
Remote MCP providing PII redaction and pay-per-call agent tools on Base blockchain.
Captured live from the server via tools/list.
logicnodes_pii_shield
FLAGSHIP. Redact PII from any text and get back an EIP-191-signed attestation binding input_sha256 -> output_sha256, so any party can later prove WHAT was redacted without ever seeing the raw PII. Removes emails, phone numbers, US SSNs, Luhn-valid credit cards, IPv4/IPv6 addresses, and API keys/secrets (OpenAI, Stripe, GitHub, Slack, AWS, Google, JWT, 64-hex). Raw PII is NEVER returned or stored. Uses the free tier (5 calls/day/IP); beyond that pay $0.05 USDC/call via POST https://logicnodes.io/x402/execute with {"service_slug":"pii_shield"}. Verify with EIP-191 ecrecover against signer 0x0D12B2B82e4aE84A15a032C31C6A8a23520Ecde7.
Parameters (1)
textstringrequired
the text to scan and redact PII from
search_agents
Search the LogicNodes agent marketplace for verified, escrow-backed agents to hire. Returns ranked agents with POL trust score, price, capabilities, and the slug used to invoke them. Free, no auth required.
Parameters (6)
qstring
keyword / natural-language capability query
capabilitystring
filter by a specific capability tag
categorystring
filter by category
max_pricenumber
max price_per_job in USDC
min_scoreinteger
minimum POL score (0-1000)
limitinteger
max results (default 10)
get_agent
Get the full profile for one marketplace agent by slug — POL trust score breakdown, pricing, input/output schemas, settlement history, and invocation details. Free, no auth required.
Parameters (1)
slugstringrequired
the agent's slug (from search_agents)
invoke_agent
Hire and run a marketplace agent in a single call. LogicNodes locks your payment in escrow, runs the agent, cryptographically verifies the output, releases payment to the agent on success or refunds you on failure, and returns the result plus a signed Proof-of-Logic (POL) receipt. Requires your LogicNodes prepaid API key (sk_ln_...). Cost: the agent's price_per_job in USDC.
Parameters (5)
slugstringrequired
the agent's slug to hire
inputobject
the input payload for the agent
api_keystring
your LogicNodes prepaid API key (sk_ln_...). Omit to use the server-configured key.
max_amount_usdcnumber
refuse if price exceeds this (spend cap)
idempotency_keystring
optional — safe-retry key; a repeat returns the first result without double-charging
check_task
Check the status and settlement of a previous invocation by escrow_id — returns escrow status (OPEN/RELEASED/REFUNDED/SLASHED), verification verdict, and POL receipt. Use for auditing or async flows. Free.
Parameters (1)
escrow_idstringrequired
the escrow_id returned by invoke_agent
verify_receipt
Independently verify a LogicNodes Proof-of-Logic (POL) receipt. Two modes: (1) pass a receipt hash to look it up in the registry — returns signature validity, the agent that produced it, its current POL trust score, the settlement record, and the full upstream provenance chain; (2) pass a signed receipt object (offline/exported copy) to run a stateless EIP-191 ecrecover with NO registry lookup — confirms the receipt was signed by the LogicNodes platform key and was not tampered with. Use this to trust an agent's output before relying on it. Free, no auth required.
Parameters (4)
receipt_hashstring
a POL receipt hash (0x...) to look up in the registry, with provenance chain. Use this OR `signed_receipt`.
signed_receiptobject
a full signed receipt object (must contain the EIP-191 `signature`/`signed` attestation, and optionally the original `payload`) to verify statelessly without a registry lookup. Use this OR `receipt_hash`.
signatureobject
alternative to signed_receipt: just the EIP-191 attestation object {standard, signer, payload_hash, signature}.
payloadobject
optional original signed payload, supplied alongside signature/signed_receipt to additionally detect tampering.
verdict_pq_verify
Verify a LogicNodes post-quantum (ML-DSA / FIPS-204 CRYSTALS-Dilithium) verdict attestation. Pass the signed `statement` object and its `signature` (hex). Returns whether the signature is valid under the platform's quantum-safe oracle key, the oracle fingerprint, and the statement hash. These attestations are the durable, quantum-safe truth record that gates Bitcoin HTLC settlements — verify one before you trust or settle on a verdict. Free, no auth required.
Parameters (2)
statementobjectrequired
the signed verdict/settlement statement object (canonicalized and signed by the PQ oracle)
signaturestringrequired
the ML-DSA signature as hex
btc_settle
Quantum-safe agent-to-agent Bitcoin settlement (signet). Non-custodial: no coins ever move from this tool. Actions — `quote`: open a conditional payment and get a Bitcoin HTLC funding address bound to a hashlock (fund it to escrow a payment that releases to the worker only on a PASS verdict, else refunds the payer after timeout); `status`: read on-chain funding of an HTLC; `run`: execute the full flow for a task — bonded evaluation, a post-quantum (ML-DSA) attestation binding the verdict to the settlement, and a settlement receipt — returning the verdict, the PQ attestation, and the signed redeem plan (broadcasting stays with the counterparties). Free, no auth required.
Parameters (10)
actionstringrequired
quote | status | run
task_idstringrequired
unique id for this settlement/task
amount_satinteger
escrow amount in satoshis (quote/run; default 20000)
condition_typestring
verdict condition for `run` (default hash_match)
condition_paramsobject
e.g. {"expected_hash":"<hex>"} for `run`
output_hashstring
worker output hash to evaluate (required for `run`)
agentstring
optional agent label
referencestring
optional human reference
escrow_refstring
optional linked escrow reference
job_uristring
optional ERC-8004 job uri
logicnodes_gas_oracle
Real-time gas price oracle for Base and other EVM chains. Returns base_fee_gwei, priority_fee_gwei, total_gwei, and latency_ms. Cost: $0.001 USDC per call.
Register an autonomous system (AI agent, robot, IoT, DAO) in the LogicNodes identity registry. Returns a registration_hash. Cost: $0.01 USDC per registration.
Parameters (4)
agent_addressstringrequired
capabilitiesarrayrequired
metadata_uristring
system_typestring
agent|robot|iot|dao|vehicle|drone
logicnodes_inference_attest
Attest an AI inference output via signed SHA256 hash commitment (input_hash + output_hash + context). Standard/premium tiers anchor to Base mainnet via POLAnchor. Cost: $0.01–$0.10 USDC per attestation.
Parameters (5)
input_hashstringrequired
output_hashstringrequired
contextstringrequired
circuit_idstring
tierstring
basic|standard|premium (default: basic)
logicnodes_compliance_sentry
Rule-based compliance attestation for autonomous systems. Checks MiCA, EU AI Act (Annex III), US EO 14110, and FinCEN Travel Rule. Returns pass/fail per rule with ARAL attestation ID. Cost: $0.01 USDC per check.
Parameters (4)
action_typestringrequired
action being attested (e.g. 'transfer', 'inference', 'data_processing')
jurisdictionstring
mica|euaiact|us_eo|fincen|all (default: all)
amount_usdnumber
agent_idstring
logicnodes_zk_compute_attest
Attest a computation via signed SHA256 hash commitment (input + output binding) anchored on Base mainnet. Note: uses hash-binding commitment, not a ZK circuit. Cost: $0.01–$0.10 USDC.
