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-meps). View diagnostics → Pass
  • Clear OSI-approved license (MIT).Pass
  • Actively maintained (last published 2 days ago).Pass
  • Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability70
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 621 tokens (~155/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
  • Stability observed for 8 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 5 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

MCP tools · 4 exposed · ~569 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
meps_conditions_for_drug ~146

What a drug is actually being prescribed for in the US population, ranked by estimated people. Answers off-label and multi-use questions that a label or an approval database cannot: what gabapentin, metformin or amitriptyline are really used to treat in practice. Give a generic drug name.

NameTypeReqDescription
drugstringyesGeneric drug name, e.g. "gabapentin", "metformin".
limitnumber–Max conditions, default 20, max 100.
min_samplenumber–Minimum survey respondents behind a row, default 60.
yearnumber–Survey year. Defaults to the most recent loaded.

No output schema declared.

No examples provided.

meps_drug_use ~109

National prescription volume and spending for one drug: how many Americans filled it, how many fills, total spend across all payers and how much patients paid out of pocket. Population-wide rather than a single programme, so it answers how widely used a medicine is in the US and what share of its cost falls on patients.

NameTypeReqDescription
drugstringyesGeneric drug name, e.g. "atorvastatin".
yearnumber–Survey year. Defaults to the most recent loaded.

No output schema declared.

No examples provided.

meps_drugs_for_condition ~214

Which prescription drugs Americans actually take for a given medical condition, with a national estimate of how many people take each one. Covers the whole US population — every payer, every age, commercial and uninsured included, not just Medicare or Medicaid. Ask with a plain condition name like "depression", "high cholesterol", "type 2 diabetes" or "asthma". Returns drugs ranked by estimated people treated, each with the survey sample behind it.

NameTypeReqDescription
conditionstringyesCondition in plain words ("depression", "high blood pressure"), or a CCSR category code like MBD002.
limitnumber–Max drugs, default 20, max 100.
min_samplenumber–Minimum survey respondents behind a row, default 60 — AHRQ's own reliability floor. Lower it to see less-common drugs, which come back marked reliable:false because AHRQ would not publish them.
yearnumber–Survey year. Defaults to the most recent loaded.

No output schema declared.

No examples provided.

meps_top_drugs ~100

The most-used prescription drugs in the United States, ranked by estimated number of people who filled them, with total and out-of-pocket spending. Answers what the most commonly taken medications in America are for a given year.

NameTypeReqDescription
limitnumber–Max drugs, default 25, max 100.
order_bystring–Ranking measure, default people.
yearnumber–Survey year. Defaults to the most recent loaded.

Common questions

What is the Meps MCP server?

Meps is an MCP server listed in the public MCP registry as io.github.pipeworx-io/meps. MEPS, what Americans actually take, and what for. This page covers its npm package (@pipeworx/mcp-meps).

Is the Meps MCP server safe to use?

Meps scores 84 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 6 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 Meps MCP server expose?

Meps exposes 4 tools: meps_drugs_for_condition, meps_conditions_for_drug, meps_drug_use, meps_top_drugs. Their descriptions and schemas cost roughly 569 tokens of context every time the server is loaded.

Is the Meps MCP server still maintained?

Meps is still listed as active in the MCP registry. We last reached this channel on 6 November 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 Meps MCP server under?

Meps 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 Meps MCP server?

VerifyMCP ran 16 checks on Meps, 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.
