Trust breakdown (7 categories)

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Supply Chain Security0
  • Malware scan not yet available for this package.Unverified
  • Known CVEs could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.Unverified
  • Install-script risk not yet assessed.Unverified
  • Dependency health could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.Unverified
Provenance & Transparency32
Schema Quality & AI Usability75
  • AI-judged instruction clarity (good).Pass
  • Tool/resource definitions use about 1320 tokens (~94/item across 14 items; 14 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management90
  • Stability observed for 27 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage67
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 0% of tool parameters carry a description.Fail
Tool Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "run_eval" implies "eval" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
  • An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Unverified: 1 category

A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

Install

How do I install the retriEVAL MCP server?

retriEVAL runs locally as a container image, launched with docker run --rm -i ghcr.io/hcarrillo001/retrieval-mcp:1.0.0. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation.

MCP tools · 14 exposed · ~1,320 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
author_metric ~70

Author a custom metric from a plain-language description (+ optional golden examples). The judge converts your criteria into explicit evaluation steps, which run as a G-Eval-style scorer in run_eval / evaluate_case.

No output schema declared.

No examples provided.

compare_runs ~85

Compare several runs across all shared metrics. fmt="markdown" (default) returns a markdown matrix; fmt="text" returns plain ASCII; fmt="image" returns a PNG grouped-bar chart.

evaluate_case ~110

Score a single output inline, without loading a golden set. The result is saved as a one-case run (golden set "inline") so it has a dashboard link; pass save=False to score without recording it.

get_budget ~30

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

ground_against_url ~164

Fetch a web page and check OUTPUT for *consistency* with it: faithfulness (every claim supported by the page) and, if a question is given, answer relevancy. Use it to ask "does my answer agree with what this page says?". IMPORTANT — this is NOT a correctness check. There are no labels here: the page is an unverified source, not ground truth. A high score means the output matches the page, not that either is right. The returned `caveat` says so on every call; surface it to the user.

load_golden_set ~84

Load a golden set from a file path, a JSON array string, or JSONL text. Field names are normalized (question->input, answer->actual_output, ground_truth->expected_output, contexts->context, passages->retrieval_context, ...).

plot_metric_trend ~119

One metric's mean score across recent runs, with a threshold reference. fmt="markdown" (default) returns a rich markdown report (tables, inline bars, case strip, distribution); fmt="text" returns plain ASCII; fmt="image" returns a PNG line chart (only useful where images display).

reset_budget ~23

Reset the cumulative spend ledger to $0 (the cap itself is unchanged).

No output schema declared.

No examples provided.

run_eval ~382

Run metrics over a set of cases. Pass `cases` with the data inline (JSON, JSONL, CSV or TSV text, or a file path) to score in a single call — nothing is stored server-side and no prior load is needed. Or pass `golden_set` to reuse a set loaded earlier with load_golden_set. Inline `cases` is preferred: named sets live only in this server process, are shared with anyone else using it, and are lost when it restarts. All cases are scored, but only the `limit` lowest-scoring cases are returned by default (3) to keep replies short; `total_cases`/`shown` tell you how many more exist — call show_run_cases to page. Pass `generator_model` (which LLM produced the outputs) and `judge_model` (which LLM scored them) so the dashboard can compare across models; judge_model defaults to the configured judge. The run is saved to history (file or Supabase). IMPORTANT FOR CALLERS: the reply includes `view_url`, a link to the full visual report. ALWAYS include that link in your response to the user, even when you summarise everything else. `summary_md` is a ready-to-render markdown block (score table + link) that can be shown verbatim. Raises if the spend cap is hit mid-run; partial spend is still metered.

Common questions

What is the retriEVAL MCP server?

retriEVAL is an MCP server listed in the public MCP registry as io.github.hcarrillo001/retrieval-mcp. LLM evals as MCP tools: score outputs for faithfulness, relevancy, and hallucination. This page covers its container image (ghcr.io/hcarrillo001/retrieval-mcp:1.0.0).

Is the retriEVAL MCP server safe to use?

retriEVAL scores 46 out of 100 on VerifyMCP. 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 retriEVAL MCP server expose?

retriEVAL exposes 14 tools: list_metrics, load_golden_set, list_golden_sets, author_metric, run_eval, and 9 more. Their descriptions and schemas cost roughly 1,320 tokens of context every time the server is loaded.

Is the retriEVAL MCP server still maintained?

retriEVAL is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
