Why people use Claude Sycophancy Detector
Stop AI Hallucinations in your codebase with Claude Sycophancy Detector
This MCP changes that dynamic. Instead of you doing the detective work, the agent's claims are automatically checked against your actual project metadata. You get a clear signal when an agent is being sycophantic, allowing you to catch errors before they ever reach your terminal.
What Vinkius changes
You stop debugging hallucinations and start working with verified code facts.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.

Before you connect
Questions about Claude Sycophancy Detector.
The practical details behind the request, access and result.
How does the Claude Sycophancy Detector prevent AI errors?
It works by comparing the technical claims an agent makes—like file paths or function names—against your actual codebase metadata to ensure they are factually correct.
Can I use this Claude Sycophancy Detector in Cursor or VS Code?
Yes, you can connect this MCP to any compatible client including Cursor, VS Code, Windsurf, and Claude Desktop to verify code assertions in real-time.
What is sycophancy in AI models?
Sycophancy is when an AI prioritizes agreeing with your stated assumptions over being factually accurate, which often leads to the agent validating incorrect code structures.
Does this MCP work with any coding language?
Yes, as long as your agent has access to the codebase metadata, this MCP can verify claims across any programming language or project structure.
How do I know if my agent is being sycophantic?
You can use the risk summary feature to get a clear, human-readable report on whether your agent is showing patterns of false agreement.
What is sycophancy in AI?
Sycophancy is when an AI model agrees with a user's incorrect statement or assumption to avoid conflict, rather than providing the correct factual information.
How does `analyze_response_accuracy` work?
The analyze_response_accuracy capability uses deterministic regex to extract claims like file paths and function signatures from a response, then compares them against the provided codebaseFacts to determine accuracy.
Which AI clients can use this capability?
This capability can be used with any MCP-compatible client, including Cursor, VS Code, Claude Desktop, and Windsurf.
