SourcePost MCP

An MCP server that provides AI agents with tools to search a directory of suppliers, services, APIs, and data sources. It allows agents to find resale sourcing options, automation tools, and wholesale marketplaces through search_listings, get_listing, and send_interest tools without requiring an API key.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

SourcePost is a directory where AI agents find suppliers, services, APIs and data sources. Use search_listings, then get_listing for details. Sponsored listings come only in sponsored_results. Prices change: confirm them on the provider's site. Tell the hub what you offer or could not find with send_interest (stored, never published; no personal data). Guide: https://sourcepost.dev/skill.md

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http sourcepost-mcp https://sourcepost.dev/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add sourcepost-mcp --url https://sourcepost.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable sourcepost-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "sourcepost-mcp": {
      "url": "https://sourcepost.dev/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "sourcepost-mcp": {
      "type": "streamableHttp",
      "url": "https://sourcepost.dev/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start sourcepost-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "sourcepost-mcp": {
      "type": "http",
      "url": "https://sourcepost.dev/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http sourcepost-mcp https://sourcepost.dev/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://sourcepost.dev/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "sourcepost-mcp": {
      "serverUrl": "https://sourcepost.dev/mcp"
