Your AI agent, now sends Solana transactions for you.
BoltTx is the first Solana transaction relay with a native MCP (Model Context Protocol) server. Tell any MCP-compatible agent what you want in plain English — BoltTx delivers it on-chain at industry-leading speed.
Send 0.1 SOL to J1k1L1X5AfgJrsWhQ1EGJmKcEFmtJd21Xq8hJQK5dYNc via BoltTx with minimum tip.
- →Checking your BoltTx account…
- →You're on Growth plan. Using 0.0005 SOL tip to BoLt5YM7…wP. Building and signing locally…
- →Submitted. Signature: 5xKnR8qXeVm3pN…
- ✓Confirmed on-chain. Done.
Why MCP matters.
MCP is how AI agents connect to real tools in 2026. BoltTx speaks it natively — the competition doesn't.
Zero code for AI users
Your AI agent handles the entire flow — fetch blockhash, build tx, add tip, sign locally, submit, confirm. You just describe what you want.
Your keys stay yours
MCP server never receives private keys. Signing happens client-side with your existing wallet or keypair. We only accept already-signed bytes.
Any MCP client
Same config format, same server, across every MCP-compatible client. Future MCP clients work automatically — no per-vendor integration required.
One npx away
Published to npm as @bolttx/mcp-server. Add one JSON block to your MCP config — no manual install, no build step.
Full tool coverage
6 tools + 3 resources expose your account, tip addresses, plan limits, send, batch send, and delivery telemetry — everything the agent needs.
Transparent tip economics
The agent sees your plan and minimum tip up front. No surprise fees, no opaque markups — the same tip-based pricing as the REST API.
The landscape
Every other Solana transaction relay still expects you (or your code) to wire the HTTP calls yourself.
| Relay | MCP server | AI agent native | Plain-English send |
|---|---|---|---|
| BoltTx | Yes | Yes | Yes |
| Other Solana relays | No | No | No |
Install in 30 seconds.
Drop this single config block into your MCP client. Replace the API key with yours from the dashboard. Restart the client. Done.

Works with any MCP client.
MCP is an open standard. As long as the client speaks the protocol, BoltTx is one config block away — no per-vendor integration, no waiting for our SDK.
Standardized config
The same JSON snippet works across every MCP-compatible client. Drop it in once.
Open protocol
MCP is an open spec. New clients adopting MCP work with BoltTx automatically.
Local-first
The MCP server runs as a local subprocess on your machine. No cloud middleman, no telemetry leaks.
