Vtimestamp Write vs Aga MCP Server
A side-by-side look at the Vtimestamp Write and Aga MCP Server MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Vtimestamp Write for cryptography work as a local process; choose Aga MCP Server for cryptography as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Vtimestamp Write when
- You need dedicated capabilities in the Cryptography domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
VERUS_CONF_PATH, VERUS_RPC_URL, VERUS_RPC_USER, VERUS_RPC_PASSWORD. - You want tools like
InvalidParams.
Choose Aga MCP Server when
- You need dedicated capabilities in the Cryptography domain.
- You prefer a local stdio subprocess transport.
- You want tools like
get_server_info, get_portal_state, init_chain.

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
Vtimestamp Write is categorized under Cryptography and uses a local stdio subprocess. Aga MCP Server belongs to Cryptography and uses a local stdio subprocess. Pick Vtimestamp Write for cryptography work and Aga MCP Server 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.
Vtimestamp Write has no declared pricing — check the project's own site. Aga MCP Server has no declared pricing — check the project's own site. 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 vtimestamp-write and aga-mcp-server as separate keys in the same mcpServers object, and your assistant will call tools from either one.
