Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Turn markdown and Mermaid diagrams into rendered jotbins.com links, and read them back.
These three are never merged into one score: opinions, measurements and popularity are different things.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
Either way works: install it on your computer or connect to the cloud version.

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

Turn a markdown file into a jotbins link that renders it.
npx jotview notes.md
Zero dependencies. No install, no account, no config.
The document is compressed and packed into the URL's fragment — the part after #. Fragments are never sent to a server, so for links 2000 characters or fewer nothing you write leaves your machine. Opening the link renders it entirely in the browser.
jotview <file> mint a link from a file
jotview read markdown from stdin jotview decode print the markdown behind a /d, /p or short link jotview mcp [--raw] run as an MCP server for AI agents
--raw never shorten; always the full /d URL --short always shorten, even when small --keep make a shortened link permanent --open open the link in your browser --copy copy the link to your clipboard --json print the result as one JSON line (see below) --base-url override https://jotbins.com -h, --help -v, --version
Examples:
jotview README.md --open
cat notes.md | jotview jotview notes.md | pbcopy LINK=$(jotview notes.md --raw) jotview decode https://surl.jotbins.com/abc123 > notes.md
decode accepts jotbins.com/d links (decoded locally), surl.jotbins.com short links (fetched; like a click, that keeps an active short link alive) and public jotbins.com/p pastes (fetched from jotbins; private pastes read as not found).
A document's link grows with the document — roughly half the markdown's size in characters. A 20 KB file produces an ~8,700-character URL, which Discord, X, and most chat clients will not accept.
So links over 2000 characters are shortened via surl.jotbins.com, and jotview tells you on stderr when that happens:
note: uploaded to jotbins to shorten (8768 → 30 chars). use --raw to keep it local.
note: short link expires after 30 days unused. use --keep to keep it forever.
Shortening uploads your document. The fragment *is* the markdown, so storing the URL stores the text. Below the threshold nothing is uploaded and no network request is made at all. Use --raw to keep a long document local, accepting a URL too long to paste into most places.
Short links clean up after themselves. One nobody opens for 30 days is deleted, with a 60-day window to bring it back from its waiting page. Pass --keep to make it permanent from the start, or click Save link on the waiting page any time before then. Full /d links are never stored, so they never expire.
If the shortener is unreachable or rate-limited, jotview prints the full link and exits 0 — it never fails your pipeline over a shortening problem.
jotview mcp is a stdio MCP server with two tools. With render_markdown an AI writes markdown — notes, a report, a Mermaid diagram — and gets back a jotbins link to hand you; with read_link it reads a jotbins link you share.
Claude Code
claude mcp add jotview -- npx -y jotview mcp
Claude Desktop — download jotview.mcpb from the latest release and double-click it. Optionally pick a docs folder it may read files from.
Cursor and other clients — add to the MCP config:
{ "mcpServers": { "jotview": { "command": "npx", "args": ["-y", "jotview", "mcp"] } } }
Then just ask: *"draw a diagram of our deploy flow and give me a jotbins link."*
`render_markdown` takes content (the markdown), plus optional title (link text instead of the first heading), keep (make a short link permanent) and shorten ("auto", "always" or "never"). It returns a ready-made markdown link, [First heading](url), and a note on whether anything was uploaded. It never reads files — the AI passes text it already has.
Rendering files. The local server can also take a path instead of content, so the AI doesn't have to paste a whole file into the tool call. It reads only .md, .markdown, .mdx and .txt files, and only inside the folder the server runs in (Claude Code starts it in your project) or a folder you allow with --allow-dir:
claude mcp add -s user jotview -- npx -y jotview mcp --allow-dir ~/notes
If the server runs in / or your home folder and no --allow-dir is given, path is switched off. The remote server never reads files.
`read_link` takes a url (a /d link, a public /p paste or a short link) and returns the markdown behind it, so you can paste a link and say *"fix the typos and give me a new link."* Links never change; an edit is a new link.
Uploads. Every character of a link costs tokens, so MCP shortens sooner than the CLI: links over 500 characters go through surl.jotbins.com, which uploads the document (short links expire after 30 days unused unless keep is set). To forbid uploads entirely, start the server with --raw:
claude mcp add jotview -- npx -y jotview mcp --raw
Works with clients on any MCP revision from 2024-11-05 through 2026-07-28.
The same tool runs at `https://mcp.jotbins.com/mcp` (Streamable HTTP, no sign-in), for clients that can't run local commands.
https://mcp.jotbins.com/mcp.claude mcp add -s user --transport http jotview https://mcp.jotbins.com/mcpSame rules as the local server, except it can't forbid uploads: use shorten: "never" per call, or the local --raw server, to keep a document off surl.jotbins.com. Uploads are rate-limited per client; over the limit you still get the full link.
The Worker lives in worker/ and deploys with cd worker && npx wrangler deploy.
stdout is the URL and nothing else. Notices, warnings, and errors go to stderr, so $(jotview x.md) and jotview x.md | pbcopy stay clean.
With --json, stdout is one JSON line instead, for scripts and CI:
{"url":"https://surl.jotbins.com/abc123","rawUrl":"https://jotbins.com/d#z:…","shortened":true,"permanent":false,"failure":null}
failure is the shortener's error when shortening was tried and failed (url is then the full link).
Exit codes: 0 success, 1 runtime error, 2 usage error.
Input is capped at 1 MB, matching what the /d renderer will open.
Node 18 or newer.
Releases run from GitHub Actions. On an up-to-date main:
npm version minor
git push --follow-tags
npm version also updates manifest.json and server.json. The v* tag then tests, publishes to npm (trusted publishing, with provenance), attaches jotview.mcpb to a GitHub release, and updates the MCP Registry entry. Move the Unreleased notes in CHANGELOG.md under the new version first (commit that before npm version). The Worker deploys separately: cd worker && npx wrangler deploy.
If a release run fails partway, fix the cause and finish it with gh workflow run release.yml -f tag=vX.Y.Z — finished steps are skipped.
