VerdictSwarm MCP

VerdictSwarm MCP Server

Retired October 7, 2026. The hosted VerdictSwarm API and MCP service are decommissioned. The published package depends on that retired API and no longer provides token checks, free keys, live pricing, or payment services. This repository preserves the implementation for reference and reuse under its existing license. The setup instructions below describe the former service.

[PyPI] [Python] [License: MIT] [MCP]

VerdictSwarm is a pre-trade security layer for agents that touch crypto. This MCP server exposes the Verdict API v2 as a small set of read-only tools for token checks, size-aware exit screening, and live pricing discovery.

Quick start

No account setup is required. If VS_API_KEY is absent, the server mints a free key on the first API-backed tool call and saves it in the platform user config directory.

uvx verdictswarm-mcp

Then ask your MCP client: “Check DezXAZ8z7PnrnRJjz3wXBoRgixCa6xjnB7YaB1pPB263 on Solana at fast level.”

To supply an existing free or credits-backed key:

VS_API_KEY=vs1_your_key uvx verdictswarm-mcp

Claude Desktop, Cursor, Windsurf, and OpenClaw

Use this server entry (the env block is optional):

{  "mcpServers": {    "verdictswarm": {      "command": "uvx",      "args": ["verdictswarm-mcp"],      "env": {        "VS_API_KEY": "vs1_your_key"      }    }  }}

Without VS_API_KEY, the self-provisioned key is stored at:

• macOS: ~/Library/Application Support/VerdictSwarm/config.json
• Linux: ${XDG_CONFIG_HOME:-~/.config}/verdictswarm/config.json
• Windows: %APPDATA%\VerdictSwarm\config.json

The file is created with user-only permissions where the operating system supports them. Set VS_CONFIG_DIR to override the directory.

Tools

The 0.1.x names scan_token, get_quick_score, check_rug_risk, get_token_report, and verify_payment are no longer advertised as MCP tools; clients see only the three current v2 tools above. An explicit call to an old name still returns a migration response and makes no legacy pay-lane request.

Free quota and x402 overflow

Free keys have per-level daily limits advertised by the API. If a limit is exhausted, the tool response says when the quota resets and preserves the complete x402 challenge. To continue immediately, set VS_API_KEY to a credits-backed key or use the returned x402 payment instructions.

The MCP client sends these attribution headers on API requests:

• X-VS-Integration: mcp
• X-VS-SDK-Version: 0.2.1

Configuration

For HTTP transport:

VS_TRANSPORT=streamable-http HOST=0.0.0.0 PORT=8000 uvx verdictswarm-mcp

Programmatic client

import asynciofrom verdictswarm_mcp import VerdictSwarmApiClient
async def main():    client = VerdictSwarmApiClient()    verdict = await client.check_token("TOKEN_ADDRESS", "solana", "fast")    print(verdict["verdict"]["action"], verdict["verdict"]["score"])
asyncio.run(main())

Development

git clone https://github.com/sentien-labs/verdictswarm-mcp.gitcd verdictswarm-mcpuv sync --extra devuv run --extra dev python -m pytest -q

The server supports Python 3.10–3.13 and both stdio and HTTP transports.

Feedback and community

Used the server in an agent, bot, wallet, or dashboard? Share the client, runtime, where the risk check fits, and what worked or failed through the VerdictSwarm community page. You can also show an integration, choose a structured issue form, or add your project to ADOPTERS.md. Praise is never required. Stars should come only from people who independently find the project useful; agents must not automate them.
