How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security98
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass

- Security-disclosure policy not yet verified: we couldn't inspect the source repository.Unverified
Schema Quality & AI Usability71
- AI-judged instruction clarity (excellent).Pass

Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 3 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "pqc_sign" implies "pay" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

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 →
attest_decision Seal an AI agent decision (VAID-1) ~279
Pay $0.05 USDC (x402) to seal an AI agent's declared decision: its input hash, output, model and timestamp are chained in an append-only Black Box and anchored on-chain (VAID-1, this server's node-bound Dilithium-2 key). You also get back a self-contained ML-DSA-65 / Dilithium-3 signature over the same canonical decision bytes for independent offline verification. Returns a re-verifiable receipt. Built for EU AI Act Art.12 record-keeping. It notarizes the decision as declared; it does not judge whether the decision was correct. Without payment_tx_hash you get the payment challenge.
| Name | Type | Req | Description |
|---|---|---|---|
| agent_id | string | yes | Stable identifier of the agent whose decision is sealed. |
| input | string | yes | The decision input (or its hash). |
| model | string | – | Model/agent version that produced the decision. |
| output | string | yes | The decision output the agent produced. |
| payer | string | – | Optional payer address hint. |
| payment_tx_hash | string | – | A confirmed USDC-on-Base transaction hash paying the required amount to the treasury. If omitted, the tool returns the x402 payment challenge (accepts[]) instead of a result — pay first, then call ag… |

pqc_sign Buy a post-quantum signature ~236
Pay $0.02 USDC (x402) for one post-quantum ML-DSA-65 / Dilithium-3 (NIST FIPS 204) signature over your message (its sha256 is signed) or a hex hash (signed directly). Returns { digest, signature, public_key, payment }. Without payment_tx_hash you get the payment challenge, not a signature. The signature proves these exact bytes were signed by this server's PQC key — nothing about their truthfulness, and 'quantum-resistant per NIST' is not 'unbreakable'.
| Name | Type | Req | Description |
|---|---|---|---|
| hash | string | – | Hex digest signed directly. Provide message OR hash. |
| message | string | – | UTF-8 string; sha256(message) is signed. |
| payer | string | – | Optional payer address hint. |
| payment_tx_hash | string | – | A confirmed USDC-on-Base transaction hash paying the required amount to the treasury. If omitted, the tool returns the x402 payment challenge (accepts[]) instead of a result — pay first, then call ag… |

seal_provenance Buy a PQC + drand provenance seal ~241
Pay $0.05 USDC (x402) for a post-quantum provenance seal over content: a drand round (League of Entropy, not backdateable) + a self-contained ML-DSA-65 / Dilithium-3 signature over the seal + an on-chain anchor attempt (this server's node-bound Dilithium-2 key) over the content hash. Useful for EU AI Act (Art. 10/50/53) provenance. It is a provenance record, not a content audit. Without payment_tx_hash you get the payment challenge.
| Name | Type | Req | Description |
|---|---|---|---|
| content | string | – | UTF-8 content; sha256(content) is sealed. |
| content_hash | string | – | Sha256 hex you already computed. Provide content OR content_hash. |
| payer | string | – | Optional payer address hint. |
| payment_tx_hash | string | – | A confirmed USDC-on-Base transaction hash paying the required amount to the treasury. If omitted, the tool returns the x402 payment challenge (accepts[]) instead of a result — pay first, then call ag… |

verify_proof Verify a post-quantum signature ~172
Verify a post-quantum (ML-DSA-65 / Dilithium-3, NIST FIPS 204) signature against its public key. Free, no payment. Returns { valid, verdict }. A valid result proves the exact bytes in signed_message_b64 were signed by the given key; it says nothing about their truthfulness. For a signature from pqc_sign over a hex digest D, signed_message_b64 = base64(utf8(D)).
| Name | Type | Req | Description |
|---|---|---|---|
| public_key | string | yes | Base64 ML-DSA-65 / Dilithium-3 public key. |
| signature | string | yes | Base64 ML-DSA-65 / Dilithium-3 signature to check. |
| signed_message_b64 | string | yes | Base64 of the exact bytes that were signed. |
No output schema declared.
No examples provided.
x402_checkout Get x402 payment requirements ~128
Return the live x402 (HTTP 402) payment requirements for a paid FractalAI resource: price, network, USDC asset, payTo address and the accepts[] entries (EIP-3009 gasless and txHash fallback). Free — it never moves funds. Use it before pqc_sign / seal_provenance / attest_decision to learn exactly how much and how to pay. Pass resource='manifest' for the full .well-known/x402.json.
| Name | Type | Req | Description |
|---|---|---|---|
| resource | string | yes | Which paid resource to price, or 'manifest' for the whole x402 manifest. |

What is the FractalAI Post-Quantum Proofs MCP server?
FractalAI Post-Quantum Proofs is an MCP server listed in the public MCP registry as io.github.johnInarti/fractalai. Post-quantum (ML-DSA-65/Dilithium-3) proof, provenance & AI-decision receipts, paid via x402. This page covers its npm package (fractalai-mcp-server).
Is the FractalAI Post-Quantum Proofs MCP server safe to use?
FractalAI Post-Quantum Proofs scores 66 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 21 September 2026. It declares no install or post-install scripts.

What tools does the FractalAI Post-Quantum Proofs MCP server expose?
FractalAI Post-Quantum Proofs exposes 5 tools: verify_proof, x402_checkout, pqc_sign, seal_provenance, attest_decision. Their descriptions and schemas cost roughly 1,056 tokens of context every time the server is loaded.
Is the FractalAI Post-Quantum Proofs MCP server still maintained?
FractalAI Post-Quantum Proofs is still listed as active in the MCP registry. We last reached this channel on 21 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the FractalAI Post-Quantum Proofs MCP server under?
FractalAI Post-Quantum Proofs declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
