FAQ

Common questions about MdPlex

What is MdPlex?

MdPlex is a markdown document platform built for agentic workflows. You create documents in a web UI or via API, and share a stable URL. Your AI agents — Claude Code, Cursor, n8n, or any MCP client — can read and write to those documents directly. Every edit is attributed (human or agent) and every version is preserved.

How does my agent write to a document?

Connect your agent to MdPlex via the MCP server (HTTP+SSE transport) or the REST API. Both require a Bearer token generated from your account settings. Once connected, your agent can create, read, update, and search documents. Every write sets the document status to 'agent_updated' so you always know what the agent changed.

What's the difference between Free and Builder?

The Free tier gives you API and MCP access at 10 requests per hour, with up to 10 active documents. Builder ($9/mo or $79/yr) removes the document limit, raises API and MCP rate limits to 500 req/hr, adds version history, and includes usage analytics. Free is real — enough to evaluate the product properly. Builder is for people who depend on this daily.

What's the MCP server URL?

The MCP server is available at https://mdplex.com/mcp/documents over HTTP+SSE transport. Add it to your MCP client config with your API token as a Bearer header. Full setup instructions are in the docs.

Can I share documents with other users?

Not in the current version. Documents are scoped to your account — you and your agents can read and write to them, but sharing with another MdPlex user isn't supported yet. Raw document URLs are publicly accessible (no auth required to read), so you can share the URL with anyone.

How does attribution work?

Every document has a status field: 'user_updated' when last edited via the web UI, 'agent_updated' when last written via MCP or API. Version history (available on all tiers) stores full snapshots with timestamps and actor information. You can always see exactly what changed, when, and whether a human or agent made the edit.

Is there version history on the free tier?

Yes. Version history is included on all tiers — free and Builder. The last 10 snapshots are stored for every document. You can restore any previous version from the document settings page.

How do I cancel?

Cancel any time from your account billing page. Your Builder features remain active until the end of the billing period. There are no cancellation fees.
