## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-epa-regulations).

  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.

## MCP tools (2)

### `epa_regulation` (~407 tokens)

Get the full text of one EPA regulation — a US Environmental Protection Agency rule codified in 40 CFR — by its citation. Returns the exact regulatory wording currently in force. Answers "what does 40 CFR 261 say", "what is the EPA regulation for X", "does the EPA require X", "read 40 CFR 60.1", "the RCRA hazardous waste rule", "the Clean Air Act / Clean Water Act regulation for X". Forgiving citation input: "261.4", "40 CFR 261.4", "§60.1", even "261.4(a)" (paragraph stripped to the section). Covers 40 CFR part 60 new source performance standards (emission standards / Clean Air Act), part 261 identification & listing of hazardous waste (RCRA), part 262 hazardous waste generators, part 122 NPDES permits (Clean Water Act), part 141 national primary drinking water regulations, part 63 NESHAP air toxics, TSCA parts (700s) toxic substances — the whole of Title 40 (air, water, waste, chemicals). This is EPA REGULATIONS (the rules/regulatory text); for EPA DATA (facility enforcement, ECHO compliance, GHG emissions) use the epa-echo / epa-emissions tools. Pass a whole part (e.g. "261" or "60") to get that part's section list. Example: epa_regulation({ citation: "261.4" }) -> exclusions from hazardous waste; epa_regulation({ citation: "40 CFR 60.1" }) -> applicability of emission standards. Keyless.

Input parameters:

- `citation` (string, required): EPA regulation citation. A section: "261.4", "40 CFR 261.4", "§60.1", "261.4(a)". Or a whole part: "261", "part 60" -> returns the part's section list.

### `epa_search` (~282 tokens)

Keyword search across EPA regulations — US Environmental Protection Agency rules in 40 CFR. Answers "what EPA regulations cover X", "the environmental regulation / EPA rule about X", "find the EPA requirement for X". Great for topics: hazardous waste identification (RCRA), emission standards and air quality (Clean Air Act), NPDES water discharge permits (Clean Water Act), drinking water standards, air toxics / NESHAP, toxic substances (TSCA), Superfund / CERCLA, pesticide registration (FIFRA), greenhouse gas reporting requirements, underground storage tanks, stormwater. Returns matching EPA regulations with citation (40 CFR), heading, excerpt, and source URL. This searches EPA REGULATIONS (regulatory text); for EPA DATA (facility enforcement, ECHO, GHG emissions figures) use the epa-echo / epa-emissions tools. Example: epa_search({ query: "hazardous waste identification" }); epa_search({ query: "emission standards", limit: 15 }). Keyless.

Input parameters:

- `limit` (number): Max results to return, 1-20 (default 10).
- `query` (string, required): Environmental-regulation topic or phrase, e.g. "hazardous waste identification", "emission standards", "NPDES permit", "drinking water", "toxic substances".

### Is the Epa Regulations MCP server safe to use?

Epa Regulations scores 81 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. 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 Epa Regulations MCP server expose?

Epa Regulations exposes 2 tools: epa_regulation, epa_search. Their descriptions and schemas cost roughly 689 tokens of context every time the server is loaded.

### Is the Epa Regulations MCP server still maintained?

### What licence is the Epa Regulations MCP server under?

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

### What did VerifyMCP test on the Epa Regulations MCP server?

VerifyMCP ran 16 checks on Epa Regulations, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
