Atla
Archived MCP server that provided a standardized interface for LLMs to interact with the Atla API for LLMJ evaluation. The Atla API is no longer active (archived July 21, 2025).
Score Breakdown
⚙ Agent Friendliness
🔒 Security
MCP server uses environment variables for secret handling (good practice). TLS enforced for API calls. However, auth lacks granular scopes and service is archived. Dependency hygiene appears reasonable (uses standard Python build tools, mypy and ruff for code quality), but no CVE scanning results available.
⚡ Reliability
Avoid When
Service is no longer available. Do not use for any new projects.
Use Cases
- • LLM response evaluation against custom criteria
