What problem does it solve?
Agents lack vetted, niche human knowledge unless you manually paste docs or risk confident wrong answers.
Who is it for?
Solo builders shipping agent products who need on-demand, paid expert knowledge without maintaining a private corpus.
Skip if: Teams that only need free public documentation, local RAG over their own repo, or workflows with no Solana/x402 budget.
What do I get? / Deliverables
After you register the server with KM_API_KEY, your agent can query the marketplace and return retrieved expertise into the coding session.
- Registered KnowMint MCP tools in your agent session
- Purchased and retrieved knowledge responses usable in downstream coding tasks

Journey fit
KnowMint is an MCP integration you add while assembling agent tooling, not a launch or ops monitor. It connects external paid knowledge APIs (x402 on Solana) into Claude Code, Cursor, or similar clients via stdio MCP.
How it compares
Paid expertise marketplace MCP, not a local embedding skill or a generic web-search plugin.
Common Questions / FAQ
Who is KnowMint for?
Indie builders and small teams using Claude Code, Cursor, or other MCP clients who want agents to pull vetted human knowledge from a marketplace instead of inventing steps.
When should I use KnowMint?
Use it during Build when you are integrating agent tooling and need domain playbooks, checklists, or expert answers you are willing to purchase per retrieval.
How do I add KnowMint to my agent?
Install @knowmint/mcp-server (Node ≥22.6.0), set KM_API_KEY, optionally KM_BASE_URL, and register the stdio MCP server in your client’s MCP config.
