PEAC Protocol vs Hindsight
A side-by-side look at the PEAC Protocol and Hindsight MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose PEAC Protocol for cryptography work over a hosted endpoint; choose Hindsight for knowledge & memory as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose PEAC Protocol when
- You need dedicated capabilities in the Cryptography domain.
- You prefer a remote HTTP/SSE transport.
Choose Hindsight when
- You need dedicated capabilities in the Knowledge & Memory domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: API key required.
- You have the keys it needs:
HINDSIGHT_API_LLM_API_KEY.

Frequently asked questions
PEAC Protocol is categorized under Cryptography and uses a remote HTTP/SSE transport. Hindsight belongs to Knowledge & Memory and uses a local stdio subprocess. Pick PEAC Protocol for cryptography work and Hindsight for knowledge & memory.
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.
PEAC Protocol has no declared pricing — check the project's own site. Hindsight is listed as free. Auth: api key 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 peac-protocol and vectorize-io-hindsight as separate keys in the same mcpServers object, and your assistant will call tools from either one.
