First indexed and scored.

## MCP tools (9)

### `list_models` (~92 tokens)

List every provider and model in the catalog, plus each provider's frontier (flagship) model.

Each model carries a `reasoning` flag (supports extended reasoning) and a `tags` list of
curated need/industry tag ids; `tags` in the result gives their labels, one-line "why"
explanations and the date they were verified. Tags are a starting point, not benchmarks.

### `suggest_models` (~29 tokens)

Suggest sibling models from the same family as the given model id.

Input parameters:

- `model_id` (string, required)

### `list_availability` (~45 tokens)

Return the current model-availability snapshot: live OpenRouter listing status
(refreshed at most every 6 hours) plus curated Bedrock/Vertex/Foundry region coverage.

### `set_policy` (~31 tokens)

Set the company policy text used to gate prompts before any model is called.

Input parameters:

- `policy_text` (string, required)

### `evaluate_prompt` (~223 tokens)

Get pre-run feedback on a prompt's clarity/specificity before running a comparison.

An explicit, separately-triggered LLM call (uses your credentials) — not run
automatically as part of run_comparison. Rate-limited independently from
run_comparison's 3-per-8h budget. Pass `creds` as {"openrouter"?: str,
"bedrock"?: {...}, "vertex"?: {...}, "foundry"?: {...}} to use Amazon Bedrock,
Google Vertex AI, or Microsoft Foundry; a bare `api_key` is treated as an
OpenRouter key. `judge_backend` picks which backend runs the evaluation.
If the operator has set server-side keys for a backend (see https://github.com/thejaredchapman/evalforge-lite/blob/main/docs/hosting-and-server-keys.md), those are used for it automatically and creds for it are not needed.

Input parameters:

- `api_key` (string)
- `creds`
- `judge_backend` (string)
- `prompt` (string, required)

### `run_comparison` (~365 tokens)

Run a set of test-case prompts against a set of models, scoring each response.

Each test case may include an optional "rubric" (scored by an LLM judge) and/or
"checks" (rule-based checks). Returns per-model grades, cost/latency stats, and an
overall verdict. Rate-limited to 3 calls per 8 hours.
Models are "<catalog id>" (OpenRouter) or "<catalog id>@bedrock" / "<catalog id>@vertex" /
"<catalog id>@foundry"; pass matching creds ({"openrouter"?, "bedrock"?, "vertex"?, "foundry"?})
or a bare OpenRouter api_key.
judge_backend picks which backend runs the judge and policy gate.
At most 4 models. priority (balanced|quality|fastest|cheapest) ranks the results;
repeats (1-3) re-sends each prompt for timing accuracy. Returns suggestions (same
provider and backend only), advice, ranking, and best_for_priority, plus a per-run
\`cost` total and, per cell, an `evaluation` (answered/quality/instruction_following/
completeness/helpfulness/safety scores, strengths, weaknesses, reasoning, overall).
If the operator has set server-side keys for a backend (see https://github.com/thejaredchapman/evalforge-lite/blob/main/docs/hosting-and-server-keys.md), those are used for it automatically and creds for it are not needed.

Input parameters:

- `api_key` (string)
- `creds`
- `judge_backend` (string)
- `models` (array, required)
- `priority` (string)
- `repeats` (integer)
- `test_cases` (array, required)

### `list_runs` (~21 tokens)

List metadata for the 5 most recent runs, newest first.

### `get_report` (~91 tokens)

Get a PDF report (base64-encoded) for a run. Defaults to the most recent run.

priority (balanced|quality|fastest|cheapest), if given, overrides the priority the
run was made with for the report's priority/best-pick line; otherwise the run's own
priority (from run_comparison) is used.

Input parameters:

- `priority`
- `run_id`

### `get_report_csv` (~41 tokens)

Get a CSV export for a run, one row per (test case x model) cell. Defaults to the most recent run.

Input parameters:

- `run_id`

## Common questions

### What is the EvalForge Lite MCP server?

EvalForge Lite is an MCP server listed in the public MCP registry as io.github.thejaredchapman/evalforge-lite. Compare text LLMs across OpenRouter, Bedrock, Vertex AI and Foundry with automated grading. This page covers its PyPI package (evalforge-lite).

### Is the EvalForge Lite MCP server safe to use?

EvalForge Lite scores 75 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 17 October 2026. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the EvalForge Lite MCP server expose?

EvalForge Lite exposes 9 tools: list_models, suggest_models, list_availability, set_policy, evaluate_prompt, and 4 more. Their descriptions and schemas cost roughly 938 tokens of context every time the server is loaded.

### Is the EvalForge Lite MCP server still maintained?

EvalForge Lite is still listed as active in the MCP registry. We last reached this channel on 17 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the EvalForge Lite MCP server under?

EvalForge Lite declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
