Microquery Mcp — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Microquery Mcp (Agent Skill) and scored it 100/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 0 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

MCP server for Microquery — ask research questions about real-world data and get actual database records back. Works in Claude Desktop, Cursor, or any MCP-compatible AI host. Claude handles the SQL; you just ask the question.
No wallet required. Auto-registers on first query and runs on $0.10 trial credit (~1,600 typical queries).
microquery-agent — autonomous agent for pipelines and cron jobs: register → deposit USDC → query → auto top-up. Use this if you want to run microquery unattended without an AI host.
The easiest paths, in order of friction:
1. Registry install Find microquery in the Claude Desktop MCP marketplace or on smithery.ai and click Install. No config editing needed.
2. `uvx` install Add one entry to ~/Library/Application Support/Claude/claude_desktop_config.json (Mac) or %APPDATA%\Claude\claude_desktop_config.json (Windows):
{
"mcpServers": {
"microquery": {
"command": "uvx",
"args": ["microquery-mcp"]
}
}
}uvx requires uv to be installed separately (astral.sh/uv). Once installed, Claude Desktop will pick it up automatically.
3. Manual install (developers) Download microquery_mcp.py from this repo and point your host at it:
{
"mcpServers": {
"microquery": {
"command": "python3",
"args": ["/path/to/microquery_mcp.py"]
}
}
}Restart Claude Desktop after editing. The server appears in Settings → Developer with a green dot when connected.
Use the same command / args pattern above. Consult your host's MCP documentation for the exact config format.

User: What were the top adverse events reported for metformin last year?
And how does that compare to 2022 and 2023?
Claude: [queries fda.faers for each year, builds trend table]
GI events (diarrhoea, nausea, vomiting) were flat 2022→2024,
then spiked sharply in 2025 — consistent with the longevity/
obesity wave hitting FAERS with a lag. Lactic acidosis stayed
nearly flat across all four years despite overall volume growth.
User: Can you cross-reference that with genomic profiles?
Claude: [queries clinpgx, clinvar, gwas — no SQL needed from user]
SLC22A1 rs628031 has a direct ClinPGx annotation for GI toxicity —
the strongest known genomic explanation for why diarrhoea and nausea
dominate the FAERS signal for metformin.~30 seconds. Free. No account. Every finding cites a rule and a line of evidence.
