PostAndShare Solana MCP

A remote MCP server providing tools for launching, auditing, and planning Solana SPL token launches. It enables agents to build unsigned transactions, check for rug-pull risks, and validate launch parameters without handling private keys, supporting non-custodial operations over x402 or Naira credit.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

What you can do with it

  • Launch a Solana SPL token with metadata and mint authority revocation
  • Audit Solana tokens for rug-pull risks and authority checks
  • Plan token launch costs and parameters before execution
  • Retrieve Solana network details and supported programs

sol_networks — Solana networks and launch cost (free)
Advertised by the server during the last successful anonymous check.

List Solana networks this API builds for (mainnet-beta, devnet), the on-chain programs used, and the exact rent + fee table for a token launch in lamports. Free — no payment required.

sol_launch_plan — Plan a Solana token launch (free)
Advertised by the server during the last successful anonymous check.

Free. Validate a Solana token launch before building it: normalises name/symbol/supply/decimals, applies a typed allow/review/deny gate, states the authority policy (mint revoked, no freeze authority by default) and returns the exact on-chain cost in SOL and USD. Use this first — it costs nothing and catches the mistakes that would otherwise be signed.

sol_token_audit — Solana mint audit (rug check)
Advertised by the server during the last successful anonymous check.

$0.003 per call. Read a Solana SPL mint's real authority state: who can mint more supply, who can freeze holders, whether the metadata is immutable, plus on-chain name/symbol/logo and a verdict with machine-readable flags. Reads the chain directly — no opinion, no blacklist.

sol_build_launch_tx — Build a Solana token launch transaction
Advertised by the server during the last successful anonymous check.

$0.02 per call. Returns a complete, unsigned Solana transaction that creates an SPL mint, writes Metaplex metadata on-chain, mints the supply to the payer and revokes the mint authority in the same transaction. NON-CUSTODIAL: the service never sees a private key — the caller signs with their own wallet. Requires a payer public key. Test on devnet first.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
