Aga MCP Server vs FractalAI Post Quantum Proofs
A side-by-side look at the Aga MCP Server 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 Aga MCP Server for cryptography work as a local process; choose FractalAI Post Quantum Proofs for cryptography as a local process. You can also run both side by side in one mcpServers block.

Aga MCP Server tools 15
get_server_infoGet AGA server info, public keys, and portal state.get_portal_stateGet current portal state, loaded artifact info, and enforcement status.init_chainInitialize continuity chain with genesis event.attest_subjectAttest subject, generate sealed Policy Artifact. Auto-loads into portal.measure_integrityMeasure subject state, compare to sealed reference. Generates signed receipt for every measurement.revoke_artifactRevoke an active policy artifact mid-session. Portal terminates on next measurement. (NCCoE Phase 3b)verify_chainVerify continuity chain integrity.generate_evidence_bundleExport the canonical SEP evidence bundle: signed PERMITTED/DENIED tool-call receipts + Merkle proofs + a mandatory signed checkpoint, for offline third-party verification (verify_bundle_offline, aga-verify, or aga-receipt-spec/verify/verify-sep.mjs). Pin gateway_public_key to prove provenance.verify_bundle_offlineVerify a canonical SEP evidence bundle offline (full §6 algorithm: structural floor, receipt signatures, chain+ordering, leaf-recompute + Merkle bijection, signed checkpoint). Pass pinned_public_key to also prove provenance.request_claimRequest disclosure of a claim. Auto-substitutes if denied.list_claimsList available claims with sensitivity levels.delegate_to_subagentDerive a constrained policy artifact for a sub-agent. Scope can only diminish, never expand.

Frequently asked questions
Aga MCP Server is categorized under Cryptography and uses a local stdio subprocess. FractalAI Post Quantum Proofs belongs to Cryptography and uses a local stdio subprocess. Pick Aga MCP Server for cryptography work and FractalAI Post Quantum Proofs for cryptography.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Aga MCP Server has no declared pricing — check the project's own site. FractalAI Post Quantum Proofs is listed as freemium — a free tier with paid plans. Auth: no auth required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add aga-mcp-server and fractalai-post-quantum-proofs as separate keys in the same mcpServers object, and your assistant will call tools from either one.
On AllMCPs, Aga MCP Server has a quality signal of 61/100 (Good) with 1 views, 0 installs and 0 GitHub stars. FractalAI Post Quantum Proofs has 44/100 (Fair) with 1 views, 0 installs and 0 GitHub stars.
