Solana MCP by Vybe

Solana MCP by Vybe is a developer toolkit for live Solana data: wallets, trades, markets, transfers, and signable swaps. The public server publishes 44 tools. Each tool calls one Vybe API endpoint.

build-swap, build-close-token-accounts, and build-withdraw-mev return an unsigned transaction to sign in your own wallet. The server does not take private keys, and it does not broadcast transactions. get-x402-access-guide returns x402 pay-per-call instructions and does not send a payment.

This repo is the directory listing, Claude plugin, and MCP registry metadata. The running server is vybenetwork/vybe-mcp-oauth-proxy. Its current version is 1.3.2.

Versions

Related MCP server: onchain-mcp

MCP endpoint

Use the streamable HTTP endpoint:

https://mcp.vybenetwork.xyz/mcp

Registry metadata (server.json) publishes the remote as:

https://mcp.vybenetwork.xyz

Clients that require an explicit MCP path (ChatGPT Developer Mode, Codex, Cursor HTTP) should use https://mcp.vybenetwork.xyz/mcp.

The public guide at docs.vybenetwork.com/docs/mcp still describes the old tools list-endpoints, search-endpoints, get-endpoint, and execute-request. Those names are not in the published tool list.

Classification on that manifest: acts on apis, finances, code, and databases, department engineering, industry software-saas, subject computing. claude plugin validate on Claude Code 2.1.138 reports the directory-only fields (displayName, icon, links, classification) as unrecognized. The plugin directory accepts them.

What this repository holds

• server.json — metadata published to the official MCP Registry (GitHub Actions). Remote URL: https://mcp.vybenetwork.xyz.

• .mcp.json — MCP server URL for the Claude and Codex plugins. Native HTTP to https://mcp.vybenetwork.xyz/mcp. No secrets.

• .codex-plugin/plugin.json — Codex plugin metadata for local install against the same MCP URL.

• .claude-plugin/plugin.json — Claude Code / Cowork plugin manifest (skills, commands, remote MCP, directory links, and classification).

Available tools

Published tools/list has these 44 tools. Pass each tool's own arguments. Do not pass a URL, path, or HTTP method.

build-swap, build-close-token-accounts, and build-withdraw-mev return an unsigned transaction. They do not sign or broadcast it. The five *-batch tools POST a list of wallet addresses and only read data.

GitHub repository name

vybenetwork/solana-mcp-vybe (starts with solana-mcp, includes Vybe).

Publish a new listing version

1. Clone or use this repo at github.com/vybenetwork/solana-mcp-vybe

2. Tag and push (the workflow sets server.json version from the tag):

   git tag vX.Y.Z
   git push origin vX.Y.Z

   server.json is currently 1.1.3. The next registry tag should be newer than that. A tag push rewrites server.json version from the tag during the workflow.

   Or run Actions → Publish to MCP Registry → Run workflow (uses the version already in server.json).

Publishing uses GitHub OIDC in Actions; no personal token secret is required.

If you use mcp-publisher login github locally and get 403 for io.github.vybenetwork/...: Git apps like Git Credential Manager are unrelated. Open GitHub → Settings → Applications → Authorized OAuth Apps, choose the app you authorized during mcp-publisher login github (device flow), then under Organization access click Grant for vybenetwork. On SAML-enforced orgs, also complete SSO for that OAuth app. Then run mcp-publisher logout, mcp-publisher login github, and publish again.

3. Verify:

   curl -sS "https://registry.modelcontextprotocol.io/v0.1/servers?search=vybenetwork" | jq .

Cursor and other directories

Use .mcp.json as the install snippet. For Cursor Directory, submit after the registry publish succeeds; use OAuth for https://mcp.vybenetwork.xyz/mcp.

Registry catalog id

server.json name: io.github.vybenetwork/solana-mcp-vybe. Display title: Solana MCP by Vybe.

Publish: push main, then git tag vX.Y.Z && git push origin vX.Y.Z, or Actions → Publish to MCP Registry.
