A side-by-side look at the Anymd and Cairn MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Anymd for file systems work as a local process; choose Cairn for file systems as a local process. You can also run both side by side in one mcpServers block.

Tools & capabilities
Anymd tools 4
inspectDocument and media evidence when Markdown is not enough. video_timeline (bounded scene/cue timeline) and render_frame (actual decoded frames), and cite_check (quote/location support, not semantic truth), are anymd Pro; PDF operations: inspect (page facts, metadata), render_page (PNG images), extract_regions (crop bounding boxes), ocr_pages / analyze_regions (configured OCR or vision provider), structure (JSON with document map, elements, geometry; profile quality|research adds trust and accessibility reports), compare (page-level diff of sources[0] vs sources[1]).outlineReturn a document heading tree with stable node ids, title paths, page/slide/chapter ranges and Markdown byte ranges. PDF bookmarks or detected headings, Word headings, PowerPoint slides, EPUB chapters and headings, HTML and Markdown. format json (default) or tree. Pass a node id to read to fetch that section.readRead any document as clean Markdown: PDF, Word (DOCX), PowerPoint (PPTX), Excel (XLSX/XLS/ODS), CSV, EPUB, HTML or a web URL, Markdown/text, images (metadata + OCR), audio/video (metadata, chapters, subtitles). Pages/slides/sheets carry <!-- page N --> style markers for citation. Long documents stop at max_tokens (default 20000) and end with a cursor to continue; choose pages with pages: "1-5,8". A directory returns its readable files.searchSearch documents for text: one file, many files, whole directories (recursive, .gitignore aware), or URLs, across every format read supports. Returns each hit as file + page/slide/sheet + a snippet with the match in bold. mode auto (default) finds the exact phrase and falls back to BM25-ranked passages when there is none; literal or ranked force one. Narrow directories with glob, e.g. "*.pdf".

list_dirList files and folders directly under a workspace-relative directory.get_file_treeReturn the nested file/folder tree under a directory (default: whole workspace).read_detailRead a file. For .uni docs returns HTML content, flattened text, and tags; for text/.md files returns raw text plus any YAML frontmatter tags & metadata.search_filesFind files/folders whose name contains `query` (case-insensitive).grepSearch file contents for `pattern`; returns {path, line, text} matches.get_file_tagsReturn a document's tags — from a .uni's tags array or a text file's YAML frontmatter.get_tag_treeReturn {tag: [file paths]} aggregated across the workspace.find_by_metaFind documents whose metadata matches all `filters` (exact, not fuzzy). Reads .uni JSON fields and .md YAML frontmatter alike. Scalar fields match case-insensitively; `tags` (or any list field) matches when every requested value is present. Example: {"status": "to-read", "project": "amazon"}.list_tasksList tasks (documents with `category: task`), sorted by due date. A task is an ordinary frontmatter note with a lifecycle; this is the task view over it. `status` defaults to the open set (todo/doing/blocked) — pass "all" to include done, or a specific status / comma-separated list. `project` and `context` (e.g. "@errand") are exact case-insensitive filters; `due_before` (YYYY-MM-DD) keeps only tasks due before that date. Each result carries derived `overdue` and `today` flags relative to the current date.digest_workspaceReturn a token-efficient map of the workspace: one entry (title, date, tags, summary) per document, grouped by `folder`, `tag`, or a metadata field like `status`/`project`. Read this before loading individual files.list_templatesList available document templates (built-ins + workspace .cairn/templates).semantic_retrieveReturn the documents most relevant to `query`. Uses embeddings when an embedding endpoint is configured (env), else lexical scoring.- +36 more on the listing page

Anymd is listed as free. Auth: no auth required. Cairn has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add anymd and cairn-4 as separate keys in the same mcpServers object, and your assistant will call tools from either one.
