fastmd.dev

Minimalist CLI-first Markdown hosting for developers and AI agents.

fastmd lets you push Markdown from terminal to a short URL in milliseconds. The same document can be consumed by humans as HTML and by machines as raw Markdown.

cat report.md | fastmd
# -> https://fastmd.dev/x7y2

---

Latest Update (v0.2.1)

• Added a standalone fastmd skill that publishes Markdown without depending on the CLI
• Added multi-client skill installer support for Claude Code, OpenCode, and Codex
• Added GitHub-visible skill install and quick-start docs

Quick Start

Publish

# Pipe mode
cat report.md | fastmd

# File mode
fastmd push report.md

Agent skill

If you use the fastmd skill in an agent environment, the skill name is just fastmd.

Expected behavior:

• first run auto-generates a local token like fmd_live_xxxx
• the skill pushes the Markdown report to fastmd.dev directly, without requiring CLI installation
• the final result is one short URL instead of a huge inline report

Typical flow:

agent finishes report -> fastmd skill loads token -> push succeeds -> URL returned

Pull raw markdown

fastmd get x7y2

Delete

fastmd delete x7y2

fastmd upgrade

Core Use Cases

1. AI External Display Large agent output is published to a clean web view instead of flooding terminal history.

2. Seamless Agent Handoff Use /:id.md to pass structured context between local and remote agents.

3. Stealth Doc Sharing Share internal docs quickly while keeping distribution controlled.

4. CI/CD Debug Snapshots Pipe failed build/test logs to a short URL for team debugging.

5. Remote Prompt Control Host prompt/state markdown centrally and let remote workers pull updates.

6. Instant Skill Report Sharing Pipe AI skill outputs (SEO audits, content drafts, reports) to fastmd and share a clean private link in milliseconds.

REST API

POST /v1/push

curl -X POST https://fastmd.dev/v1/push \
  -H "Content-Type: application/json" \
  -d '{"content":"# Hello\nWorld","token":"fmd_live_xxxx"}'

Response:

{"id":"x7y2","url":"https://fastmd.dev/x7y2"}

GET /:id

Human-friendly HTML view.

GET /:id.md

Raw Markdown view for agents and scripts.

DELETE /v1/:id

curl -X DELETE https://fastmd.dev/v1/x7y2 \
  -H "Authorization: Bearer fmd_live_xxxx"

GET /v1/version

curl https://fastmd.dev/v1/version

Token & Privacy Model

• First run generates token like fmd_live_xxxx
• Token is saved locally at ~/.config/fastmd/token
• Server stores only token hash (SHA-256), never raw token
• Token ownership controls delete permission
• Detail/raw pages return no-index directives for privacy-first sharing

Skill flow follows the same model: first use bootstraps the token locally, and later pushes reuse the same token automatically.

Skill and CLI are separate products, but they share the same local token file at ~/.config/fastmd/token.

Skill Source

• Skill source: skills/fastmd
• Installer: install-skill.sh
• Main skill entry: skills/fastmd/SKILL.md
• Runtime helper: skills/fastmd/scripts/publish.sh
