MCP server for TypeSafe Jev: typed classify, score, check, match and screen for any agent, with confidence on every answer
Jev provides typed judgments over a closed answer set in about 130 ms, with no text generation, through TypeSafe.
Set TYPESAFEAPIKEY in the environment used by your MCP client, then run:
Replace ... with the key value. Passing it through the client environment keeps it out of tool arguments and request state.
The scripts/register.sh helper requires Bash 4+; do not run it with sh. Apply mode reads TYPESAFEAPIKEY from the environment and refuses to change client configuration when it is unset. --apply writes the plaintext key into ~/.codex/config.toml and the Claude Code user config. The key is briefly visible in the process list while claude mcp add runs because that command receives it as an argument. On Windows, use scripts/register.ps1; it restricts the resulting configuration files to the current user and keeps a .bak copy before rewriting an existing Codex configuration.
The install examples pin the public v0.2.1 tag. Omitting the tag tracks the repository's default branch instead.
