Server-provided instructions

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

OmniPost turns one post into native posts for 14 platforms. Free: omnipost_platform_specs, omnipost_validate, omnipost_share_intents, omnipost_payment_contract. Paid via canonical x402 v2 (USDC on Base): omnipost_fanout, omnipost_media_pack, omnipost_publish — call once without payment_signature to get the challenge, then retry with it. Failed jobs are never charged.

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 omnipost-mcp-vercel https://sml-omnipost.vercel.app/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 omnipost-mcp-vercel --url https://sml-omnipost.vercel.app/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable omnipost-mcp-vercel in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "omnipost-mcp-vercel": {
      "url": "https://sml-omnipost.vercel.app/mcp"
