ChemCP vs Fda Devices

A side-by-side look at the ChemCP and Fda Devices MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.

  • fda_device_510k_searchSearch FDA 510(k) premarket notifications by device, applicant, product code, K number, review panel, clearance type, decision, applicant location, third-party review status, or device-category text (via `indication`). Covers IN VITRO DIAGNOSTIC (IVD) tests and diagnostic devices, not just implants/hardware -- includes cleared molecular, genomic and companion diagnostic tests. Clearance means FDA found substantial equivalence; it is not an FDA approval or endorsement. `indication` is a BEST-EFFORT bridge, not a clinical-claim search: 510(k) records carry no indication/intended-use text at all, so it matches FDA's device CLASSIFICATION category name/definition instead (a product TYPE like "Insulin Pump", not a specific claim) and finds clearances under the matching product code(s) -- for a true clinical-indication text search (e.g. molecular/companion-diagnostic claims), use fda_device_pma_search's indication argument, which searches FDA's real approval-order narrative. Unknown arguments are rejected, not ignored. The most recent decision available lags roughly 2 weeks behind FDA's own site (openFDA's publishing cadence, not ours) -- do not treat this as same-day. `total` can exceed the 100-row `limit` cap; page further rows with `skip`.
  • fda_device_510k_summaryGet the FDA 510(k) summary/statement document and FDA review (decision memo) for one clearance, by K number — the actual filing, not just the "a document exists" flag from fda_device_510k_search. Shows the predicate device claimed and the testing behind the equivalence finding. Older/paper-only clearances were never digitized; that returns summary_available:false with a reason, not an error.
  • fda_device_pma_searchSearch FDA Premarket Approval (PMA) decisions and supplements by trade/generic name, applicant, product code, PMA number, or CLINICAL INDICATION/condition text (via `indication`). Which diagnostic tests are FDA-approved: covers high-risk IN VITRO DIAGNOSTIC (IVD) tests approved via PMA, including companion diagnostics and molecular residual disease (MRD) / ctDNA monitoring tests (e.g. Signatera, Guardant360 CDx) -- these are FDA-approved tests, not cleared devices, so this tool (not 510(k)) is the one that finds them. `indication` matches free text in FDA's own published approval-order narrative (`ao_statement`) -- the intended-use/indication language FDA wrote when it approved the device -- so a caller who describes what a test DOES or what condition/biomarker it monitors (without knowing any brand name) can still find it; `device` only matches the trade/generic NAME field and returns nothing for a condition-only question. Supplements may represent manufacturing or labeling changes rather than new devices, so a supplement's own ao_statement can be a narrow procedural note (e.g. "approval of a post-approval study protocol") rather than the full clinical indication -- pass several synonymous indication phrases (FDA's exact wording varies by product and rarely matches a lay term) rather than one exact phrase.
  • fda_device_recallsSearch FDA medical-device recall records by firm, product, product code, K number, status, or date. A recall record describes a correction/removal action and does not by itself establish patient harm.
  • fda_device_adverse_eventsSearch FDA MAUDE medical-device reports by manufacturer, brand/device, product code, event type, or PMA/510(k) number. MAUDE reports are unverified signals: they cannot establish causation, incidence, prevalence, or comparative safety.
  • fda_device_event_countsAggregate MAUDE reports for a device query by event type, manufacturer, product code, or receive date. Counts reflect reporting and database artifacts—not event rates or causal risk—and must not be compared without exposure denominators.
  • fda_device_company_profileBuild a bounded FDA regulatory snapshot for one device company across 510(k), PMA, recalls, and MAUDE. Dataset name matching is imperfect and MAUDE counts are signals, not safety rates.
  • fda_device_classificationLook up FDA device classification and regulatory context by product code, device name, or regulation number. Classification describes the product-code category, not a specific product’s clearance or approval.
  • fda_device_udi_searchSearch FDA GUDID/UDI records by brand, company, device identifier, or product code. A UDI record describes an identified device in GUDID; it does not establish current sales, availability, clearance, approval, or safety.
  • fda_device_establishment_searchSearch FDA device registration/listing data by firm, registration number, product code, or listing number. Registration/listing does not mean FDA approval, clearance, certification, or endorsement.
  • fda_device_product_code_profileBuild a bounded cross-dataset snapshot for one FDA product code: classification, recent 510(k)s, PMAs, recalls, and MAUDE reports. Dataset counts have different meanings; MAUDE counts are not event rates.

Frequently asked questions

ChemCP is categorized under Biology & Bioinformatics and uses a local stdio subprocess. Fda Devices belongs to Biology & Bioinformatics and uses a local stdio subprocess. Pick ChemCP for biology & bioinformatics work and Fda Devices for biology & bioinformatics.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.

ChemCP has no declared pricing — check the project's own site. Fda Devices has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.

Yes. MCP clients support multiple servers: add chemcp and fda-devices as separate keys in the same mcpServers object, and your assistant will call tools from either one.

On AllMCPs, ChemCP has a quality signal of 40/100 (Fair) with 1 views, 0 installs and 2 GitHub stars. Fda Devices has 61/100 (Good) with 2 views, 0 installs and 0 GitHub stars.
