Comparison
Halmos Labs and Scientist.com
Scientist.com offers public supplier and site browsing and an anonymous MCP endpoint. Halmos Labs is building source-linked lookup that keeps company and site evidence distinct.
| Topic | Halmos Labs | Scientist.com |
|---|---|---|
| Use without signup | No public access. | Contract Research Map and PharmaObservatory supplier profiles are viewable without login; the marketplace has a separate sign-in. |
| Search | Searches provider names, published site methods, equipment, materials and standards, and captured source text. | The public MCP query searches supplier names; its service filter uses broad service areas, and its country and region filters refer to headquarters. Other Scientist.com search surfaces may differ. |
| Assay at a specific lab | Site filters match only methods and equipment published for that site. A match in captured text can point to a company but does not establish a facility capability. | Maps and lists individual supplier sites; providers without known sites are not listed. Public MCP location filters refer to headquarters. |
| Agent access | The same lookup is available over HTTP API and MCP, with source links and captured text where available. | An anonymous public MCP endpoint supports search and map queries, limited to 30 calls per day and 10 per 10 minutes per IP. These limits apply to that endpoint only. |
| Data scope | 17 structured facilities plus a broader company and source archive. | A supplier directory of more than 16,000 located suppliers drawn from the Scientist.com marketplace; the wider biomedical platform also consolidates many public registries. |
| Reuse terms | No public access or reuse terms are offered. | Bulk automated extraction, scraping or republishing requires written permission. |
Best fit
For broad, public supplier and site browsing, or anonymous MCP queries within its limits, use Contract Research Map. Halmos Labs is aimed at lookups where each result shows its supporting source and whether it applies to a company or a specific site.
