bowmark-mcp 0.1.0

Bowmark MCP over stdio — a thin bridge to the hosted Bowmark MCP at https://api.bowmark.ai/mcp

bowmark-mcp — Bowmark MCP over stdio

Bowmark gives agents pre-computed navigation recipes for public websites (skip explore-and-discover). The canonical server is hosted, streamable HTTP, no auth required: https://api.bowmark.ai/mcp.

This package is a thin stdio bridge to that hosted server, for MCP hosts whose client only speaks stdio (for example browser-use's MCPClient). Tool schemas, descriptions, and results pass through verbatim — the hosted server stays the single source of truth; nothing is reimplemented here.

mcp-name: ai.bowmark/bowmark

Use

uvx bowmark-mcp        # or: pipx run bowmark-mcp / python -m bowmark_mcp

Example — browser-use:

from browser_use.mcp.client import MCPClient

bowmark = MCPClient(server_name="bowmark", command="uvx", args=["bowmark-mcp"])

Example — any MCP host config:

{ "mcpServers": { "bowmark": { "command": "uvx", "args": ["bowmark-mcp"] } } }

If your host speaks streamable HTTP, skip this bridge and connect directly to https://api.bowmark.ai/mcp.

Environment

Var	Meaning
BOWMARK_MCP_URL	Target MCP URL. Default https://api.bowmark.ai/mcp?s=p (?s=p attributes the install to the PyPI bridge). Point at http://localhost:3001/mcp for a local Bowmark API.
BOWMARK_API_KEY	Optional. Forwarded as X-Bowmark-Key; a free key (bowmark.ai dashboard) raises the anonymous per-IP daily synthesis cap to your plan budget.

Design notes (repo-internal)

• One remote session per request, retried once. streamablehttp_client is an anyio-scoped context manager; holding one session across handler tasks trips "exit cancel scope in a different task". The hosted MCP is stateless, so a fresh session per request is semantically identical and costs one initialize round-trip — noise next to an ask synthesis.
• Pass-through only. No tool logic lives here; the agent-surfaces sync rule in the root CLAUDE.md is unaffected because descriptions/schemas ride through from apps/api/src/routes/mcp.ts.
• ?s=p source code is registered in apps/api/src/mcp-sources.ts + mcp-registry/sources.json (PyPI stdio bridge channel).
• The mcp-name: ai.bowmark/bowmark line above is load-bearing: the official MCP Registry validates PyPI package ownership by finding that marker in the package README. Don't remove it.
• Versioning is manual (this is a thin bridge, not the api): bump pyproject.toml when it changes. Not wired into release-please.

Tests

cd packages/mcp-stdio
uv run --with pytest --with-editable . pytest -q

Network-free (the remote hop is monkeypatched). A live smoke against prod:

uv run --with-editable . python - <<'EOF'
import asyncio, bowmark_mcp
async def main():
    tools = await bowmark_mcp.list_tools_impl()
    print([t.name for t in tools])
asyncio.run(main())
EOF

Publishing to PyPI (manual, Christopher)

1. cd packages/mcp-stdio && uv build
2. uv publish (needs the PyPI token; mirror it to 1Password when minted).
3. After the package is live, add a packages entry (registryType pypi, identifier bowmark-mcp, transport stdio) to mcp-registry/server.json and republish — the registry validates ownership via the mcp-name marker above, so it must come AFTER the PyPI publish. See mcp-registry/README.md.
