Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account gra-kir for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

SolSigs MCP gives an AI assistant 23 Solana on-chain data tools, paid per call through x402 micropayments, plus a rug-screen token verdict.

What you can do: Query Solana on-chain data through 23 tools covering tokens and related on-chain information, as described in the registry entry. Request a rug-screen verdict on a token to help judge whether it looks risky. Calls are billed individually through x402 micropayments rather than a subscription.
When to use it: Useful when an assistant needs Solana on-chain data or a quick risk check on a token, and you accept paying per call. Less suitable if you want a free, offline, or non-financial tool.
Requirements: Runs as a local Python package (solsigs-mcp) over stdio on a desktop machine. No authentication, environment variables, or headers are declared, but x402 micropayments imply a funded payment setup, which the input does not specify.

Before you install

Calls incur x402 micropayments, so usage spends money; set limits before letting an assistant call tools freely. The rug-screen verdict is a risk signal, not investment advice. No credentials are declared, but payment-related configuration may still be sensitive.

Installation

In SourceWeft

Open SolSigs MCP in the dashboard and add it to a workspace.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Tools
