MCP server for Dutch & European legal search — 12 sources, citation-verified answers
LegalMike's Model Context Protocol (MCP) server gives your AI assistant access to Dutch and European legal sources. Ask a legal question and receive a grounded, citation-backed answer in seconds.
You can connect LegalMike to Claude on Claude.ai, the Claude desktop app, and Claude Code.

LegalMike's MCP server provides tools to search Dutch and European legal sources and synthesize grounded answers. Your AI assistant can call these tools directly — every claim in the response is backed by a citation to the original source. You don't need to learn the tools yourself; your AI client discovers and invokes them automatically based on your questions.

Every answer is grounded in text chunks retrieved from these authoritative sources. Citations link directly to the original documents on their official platforms.
The Model Context Protocol is an open standard for connecting AI clients to external tools and data. LMCP implements Streamable HTTP transport with SSE for progress notifications.
Streamable HTTP. The endpoint is /mcp. The server
returns a session ID on initialization. Progress updates and
confidence scores are sent as SSE notifications during tool
execution.
After each answer, the server sends
CONFIDENCE:{level}|{cited}/{provided}|{utilization}%.
level is high, medium, or
low. cited/provided shows how many source
chunks were referenced vs. retrieved. utilization% is
the ratio. Low confidence typically means a hallucinated citation
was detected.
Pass conversation_history (array of
{role, content} objects) to enable follow-up detection
and context reconstruction. The server detects topic switches and
treats them as new questions automatically.
No. Questions and answers are not persisted and are not used for model training.
GET /status returns
