Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

bowmark skill

LM Studio — GitHub strips a raw lmstudio: link, so this one is a paste, not a button. Copy it into your browser's address bar:

lmstudio://add_mcp?name=bowmark&config=eyJ1cmwiOiJodHRwczovL2FwaS5ib3dtYXJrLmFpL21jcC9iYWRnZS1sbXN0dWRpbyJ9

The skill for Bowmark — the web as callable functions. The agent reads a typed function library, writes a short script against it, and Bowmark runs it on the live sites.

npx skills add bowmark-ai/skill

Works on any host that supports the SKILL.md standard — Claude Code, Codex (which adopted the standard natively), Cursor, GitHub Copilot, OpenCode, and others.

The skill calls Bowmark's MCP server — wire that up at bowmark.ai/#install or via Smithery.

Want both in one step? On Claude Code and Codex, install the plugin instead — it bundles this skill and auto-wires the MCP:

# Claude Code
claude plugin marketplace add bowmark-ai/plugin && claude plugin install bowmark@bowmark-ai
# Codex
codex plugin marketplace add bowmark-ai/plugin   # then `codex /plugins` to install

Tools

ToolWhat it does
get_libraryRead the typed function library for a task or a site. Read-only, touches no site, and an unrecognized query returns the index rather than an error.
runExecute a short async JavaScript script against the live sites and return { ok, result, logs, error, ms }.
reportTell Bowmark what it could not do, or which run came back wrong. Recorded as feedback; retries nothing.

No MCP client? The same two calls are plain HTTP — GET https://api.bowmark.ai/v1/library?query=… and POST https://api.bowmark.ai/v1/run, both taking Authorization: Bearer $BOWMARK_API_KEY. The reference is bowmark.ai/docs/api; worked examples are at bowmark.ai/docs/scripting#no-install-at-all.

OpenAI Apps (ChatGPT plugin) variant

The ChatGPT Apps submission takes a skill as a ZIP or folder, and its needs differ slightly from the general skill: the plugin always ships the MCP alongside the skill, and ChatGPT exposes the tools under bare names. So there's a tailored variant, generated from this same canonical skill — never hand-maintained:

  • Folder: openai/bowmark/ — a content mirror of bowmark/SKILL.md with the trailing "Your API key" section and everything after it dropped (ChatGPT signs in by OAuth and cannot send a key), tool names rewritten to bare get_library / run, Claude-only frontmatter/tool-name references trimmed, and the three secret tools (list_secrets, request_secret, get_secret_link) replaced by the dashboard — the plugin's MCP is the ChatGPT directory connector, which does not offer them. That step refuses to build if the canonical wording moves out from under it. build-openai.mjs is the authority on what it cuts; this line described sections that have never existed in bowmark/SKILL.md, and a newcomer went looking for one.
  • ZIP: openai/bowmark-openai-skill.zip — the same folder zipped, ready to drop straight into the ChatGPT "Skills" uploader. A committed artifact (not built in CI: the release runner has no zip binary), so it rides the mirror to bowmark-ai/skill at a stable raw URL like any other file.

Both are generated by build-openai.mjs. Edit bowmark/SKILL.md, then regenerate and commit — never edit the openai/ copies directly (CI's check:openai fails a PR whose text mirror is stale):

pnpm -F @bowmark/skill sync:openai        # regenerate openai/bowmark/SKILL.md
pnpm -F @bowmark/skill build:openai-zip    # rebuild openai/bowmark-openai-skill.zip (commit it)
