markymark

What it does

markymark is a high-performance language server and AI agent tool designed for Markdown and structured data files. It enables AI agents to treat a knowledge base of documents like a codebase, providing precise navigation, cross-document indexing, and semantic search capabilities across Obsidian and Logseq-style notes.

Tools

• documentSymbol: Extracts the structure and outline of a document before reading.
• hover: Retrieves heading backlinks and key path information for specific lines.
• semanticSearch: Ranks sections by relevance using embeddings for high-precision discovery.
• findReferences: Identifies every document linking to a specific heading or symbol.
• renameSymbol: Updates headings and all their references across the entire workspace.

Installation

Install via cargo:

cargo install markymark-cli

Then add to your MCP configuration:

{
  "markymark": {
    "command": "markymark-cli",
    "args": ["mcp"]
  }
}
