OpenQFR
Description
Search machine-readable quantitative strategy failure evidence before repeating failed research.
What our measurements say
OpenQFR is a remote MCP server published at openqfr.dev. It has been probed 6 times since 9/12/2026. It answered in 6 of them (100.0%), a near-uninterrupted record. Median response time is 472 ms, placing it among the faster endpoints. It offers a narrow, focused set of 3 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.
Agent readability score
Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.
Agent readability score
Strengths
- Tool names clearly indicate their primary functions (search, retrieve, stats).
- Descriptions provide context for when tools should be used.
Weaknesses
- qfr_search parameters are all optional without guidance on required combinations.
- No documentation of error handling or constraints for any tool.
- Descriptions could better explain parameter relevance for different use cases.
qfr_search— All parameters are optional but no guidance on required combinations for effective searches.qfr_get— No error handling documentation for invalid record_id inputs.qfr_stats— No explanation of what happens if no records exist in the database.
