How do I let an agent navigate a directory of markdown docs — searching for keywords, pulling out specific sections, listing the heading structure, and extracting code examples — through MCP?

Recipe: Navigate markdown docs with mcp-server-markdown via stdio
Server: mcp-server-markdown v1.0.0 (npm: npx mcp-server-markdown) SDK: @modelcontextprotocol/sdk v1.29.0 Transport: stdio — NDJSON framing (newline-delimited JSON, NOT Content-Length). Each message is JSON\n. Tools: 6 tools — list_files, search_docs, get_section, list_headings, find_code_blocks, get_frontmatter Prereqs: None beyond Node.js. Works on any directory containing .md files.
Tool inventory
| Tool | Input | What it does |
|---|---|---|
list_files | { directory } | Recursively finds all .md files, returns sorted relative paths |
search_docs | { directory, query } | Case-insensitive full-text search across all .md files. Returns file:line matching-text. Max 50 results. |
get_section | { file, heading } | Extracts content under a heading until the next same-or-higher-level heading |
list_headings | { file } | Lists all headings as an indented TOC with line numbers |
find_code_blocks | { file, language? } | Finds fenced code blocks, optionally filtered by language tag |
get_frontmatter | { file } | Parses YAML frontmatter between --- delimiters |
Latency
- Initialize: ~509ms (cold npx start)
- tools/list: ~2ms
- Each tool call: ~1ms (all local filesystem operations)
- 5 sequential tool calls: ~7ms total
Typical agent workflow
list_files→ discover docs structuresearch_docs→ find where a topic is discussedlist_headings→ understand document structureget_section→ extract exactly the content neededfind_code_blocks→ pull out runnable examples
