What our measurements say
ablaut is a remote MCP server published at api.ablaut.dev. It has been probed 7 times since 9/10/2026. It answered in 7 of them (100.0%), a near-uninterrupted record. Median response time is 800 ms, a delay an agent will notice. 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 function (e.g., 'conjugate' for verb conjugation).
- Descriptions explicitly explain use cases (e.g., 'reverse lookup' for 'find_infinitive').
- Language coverage and validation methods are transparently documented.
Weaknesses
- Parameter schemas lack explicit type definitions (e.g., 'infinitive' input format not specified).
- No explicit error handling or constraint documentation for edge cases.
- Tool 'list_languages' lacks clarity on maturity status implications for users.

Advice
Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
- tools/list schema valid
- inputSchema is valid JSON Schema
- Smoke test passed · last run:
- Cold-start: cold 155ms → warm 142ms (penalty 13ms)
