Highlights
- Five tools: decide (shared state and named questions), classify, verify, rerank, and list_models.
- JEV_PROVIDER defaults to openrouter; set JEV_PROVIDER=typesafe with TYPESAFE_API_KEY to call TypeSafe directly.
- Ships as platform archives (Linux, macOS, Windows; amd64 and arm64), a GHCR container, or a go install.
- Requests have a 30-second timeout, a 1 MiB input limit, and a 2 MiB response limit; paid calls are never retried.
- Listed in the MCP Registry as io.github.freepik-company/jev-mcp; classify and verify preserve input order.
Watch out
Apache-2.0, but it needs an OpenRouter or TypeSafe credential, and provider errors surface only the HTTP status, so failures are opaque to debugging. Reranking evaluates every candidate before top_k filters, and verification is a model judgment, not proof or approval; no automatic acceptance thresholds are imposed.
Questions about this entry
Short answers drawn from the linked project or page.
A shared state plus named questions: choice selects a supplied option, noul returns P(true), and score returns a probability-weighted rubric index. The raw typed answers and provider metadata are returned, and the full provider output is preserved, including score legends and usage.cost when available.
classify returns a category per item with confidence and probabilities; verify returns supported, contradicted, or insufficient_evidence per claim against supplied evidence; rerank scores candidates for a query on a 0-4 rubric in descending order, with top_k filtering after every candidate is evaluated.
Pick one: download the platform archive from Releases and verify it against checksums.txt, pull ghcr.io/freepik-company/jev-mcp:latest for Docker, or run go install github.com/freepik-company/jev-mcp/cmd/jev-mcp@latest. Then put jev-mcp on your PATH and register it over stdio.
In the server environment only, never in tool arguments. JEV_PROVIDER selects openrouter (default) or typesafe; OPENROUTER_API_KEY, TYPESAFE_API_KEY, or an API_KEY override supplies the credential, and BASE_URL must be HTTPS except on loopback.
A 30-second timeout, a 1 MiB input limit, and a 2 MiB response limit; unknown input fields and incomplete or inconsistent answers fail the call; and paid calls are not automatically retried. Provider errors surface only their HTTP status, never the response body.
The Glama listing carries an Official badge, while the licence section describes the project as an independent client of TypeSafe's products. It is also listed in the MCP Registry as io.github.freepik-company/jev-mcp, so registry-browsing clients can install it from there.
list_models takes no arguments and returns compatible model IDs and the configured default, using OpenRouter's decisions catalogue or TypeSafe's native catalogue, without inference. JEV_MODEL defaults to jev-latest and can be overridden per tool call.
