A side-by-side look at the Accord Trace and FractalAI Post Quantum Proofs MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Accord Trace for cryptography work over a hosted endpoint; choose FractalAI Post Quantum Proofs for cryptography as a local process. You can also run both side by side in one mcpServers block.
accord_trace_create_proof, accord_trace_verify, accord_trace_get_proof.FRACTALAI_BASE_URL.Rows where the two servers differ are marked.

accord_trace_create_proofCreate an AccordTrace hash-bound service record. If issuer signing is configured, the proof also carries an Ed25519 issuer signature. Submitted content is not stored.accord_trace_verifyVerify an AccordTrace recorded proof, optionally compare supplied data/hash, and verify an issuer signature when one is present.accord_trace_get_proofRetrieve public non-secret AccordTrace proof metadata by proof ID.accord_trace_hashCompute AccordTrace canonical SHA-256 for JSON-compatible data without creating a proof.accord_trace_network_capabilitiesRead the live one-level AccordTrace Agent Affiliate Network policy, economics, anti-downline rules and payout activation status. Read-only; it does not enroll or attribute an agent.accord_trace_network_statsRead aggregate live affiliate-network states, distinguishing generated invitations, attributions, qualified direct sales, earned commissions and paid commissions.accord_trace_passport_product_capabilitiesRead the live Agent Passport Certificate product price and commercial readiness gates. Read-only; it never initiates checkout.accord_trace_wallet_capabilitiesRead machine-facing Agent Wallet feature gates, Ed25519 signing contract, funded-balance policy, USDC representation and explicit no-credit/no-lending boundary. Read-only; it never creates a wallet or moves funds.accord_trace_resolve_referralResolve a direct AccordTrace referral code to its active public referral record and disclosure without reserving attribution or creating a sale.No tool names declared yet. Check the project README from the listing page.
Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
