Category Health and Science
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 Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-codex-mrl). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 4 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability81
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 641 tokens (~106/item across 6 items; 6 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
- Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 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
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

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 →
codex_commodity_mrls ~98
List every pesticide with a Codex maximum residue limit in one food, with the limit for each. Accepts a commodity id, a Codex commodity code ("FP 0226"), or a food name. Use to answer which pesticide residues are permitted in a given food and at what level.
| Name | Type | Req | Description |
|---|---|---|---|
| commodity | string | yes | Commodity id ("139"), Codex code ("FP 0226"), or food name ("apple"). |
No output schema declared.
No examples provided.
codex_commodity_search ~92
Find food commodities in the Codex pesticide residue database by name (apple, rice, milk, poultry meat). Returns each match with the id needed to look up every pesticide limit that applies to it. Codex splits foods finely — "apple" and "apple pomace, dried" are separate commodities with different limits.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | Food or commodity name, e.g. "apple". |
No output schema declared.
No examples provided.
codex_pesticide_mrls ~102
Get the internationally agreed maximum residue limits for one pesticide across every food commodity Codex has set a limit for, plus its Acceptable Daily Intake, the chemical definition of the residue being measured, and its pesticide class. Accepts a pesticide name or a numeric id. Use to answer how much of a pesticide is legally permitted in foods.
| Name | Type | Req | Description |
|---|---|---|---|
| pesticide | string | yes | Pesticide name ("glyphosate") or numeric id ("158"). |
No output schema declared.
No examples provided.
codex_pesticide_search ~93
Find pesticides in the Codex Alimentarius residue database by name or partial name (glyphosate, chlorpyrifos, 2,4-D). Returns each match with the id needed to fetch its maximum residue limits. Use when you have a pesticide name and want its Codex record.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | Pesticide name or fragment, e.g. "glyphosate". |
No output schema declared.
No examples provided.
codex_vetdrug_mrls ~123
Get the Codex maximum residue limits for one veterinary drug, broken down by animal species and tissue (cattle muscle, liver, kidney, milk; fish fillet; poultry eggs), with its functional class and the JECFA evaluations behind each limit. Accepts a drug name or numeric id. An empty limit list is meaningful — Codex sets no MRL for substances like chloramphenicol that it judges unsafe at any level.
| Name | Type | Req | Description |
|---|---|---|---|
| drug | string | yes | Veterinary drug name ("abamectin") or numeric id ("1"). |
No output schema declared.
No examples provided.
codex_vetdrug_search ~76
List or search the veterinary drugs for which Codex has adopted maximum residue limits in animal-derived food — antibiotics, antiparasitics, growth promoters. Omit the query to list all of them with the year each was last adopted.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | – | Drug name or fragment. Omit to list all. |
No output schema declared.
No examples provided.
