# Agent Margin Router (remote · agent-margin-router-production.up.railway.app) 38 x402 pay-per-call tools for AI agents (USDC/USDT on Base): web, crypto, on-chain, geo, packages - Trust score: 67/100 (medium) - Change this week: +3 - Registry status: active - Liveness: live - Owner verified: no - Last scored: 2026-09-20 ## Components - remote · `agent-margin-router-production.up.railway.app`: 67/100 (this document), [markdown](https://verifymcp.io/servers/agentmarginrouter-agent-margin-router/agent-margin-router-production.md), [page](https://verifymcp.io/servers/agentmarginrouter-agent-margin-router/agent-margin-router-production) ## Channel facts - Endpoint: `https://agent-margin-router-production.up.railway.app/mcp` - Transports: `streamable-http` - Auth: `none` - Version: `0.6.0` ## Trust breakdown How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog) Scored 2026-09-20. - **Endpoint Security**: 57/100 - The endpoint's TLS certificate is valid, in date, and uses a strong key. - Authorisation not fully verified: no authorisation is required to call this server, and 53 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. - HTTPS is enforced; there's no plaintext access path. - HSTS check failed: the Strict-Transport-Security header is absent. - DNSSEC check failed: this domain isn't protected by DNSSEC. - **Transport & Reachability**: 100/100 - Verified streamable-http transport via a live MCP handshake. - **Schema Quality & AI Usability**: 68/100 - AI-judged instruction clarity (excellent). - Context-footprint check failed: tool/resource definitions use about 9985 tokens (~188/item across 53 items; 53 tools + 0 resources), over budget; trim descriptions and params. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 30/100 - Stability observed for 9 of 30 days with no destabilising changes; credit accrues until the full window elapses. - **Tool Coverage**: 100/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 100% of tool parameters carry a description. - Structured output schemas are declared (100% of tools); any adoption earns full credit. - **Tool Safety**: 100/100 - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured. - We read all 53 captured tool definition(s), and no name or description among them implies an irreversible operation. - An AI judge read all 54 captured unit(s) of tool text and found none that tries to manipulate the model reading it. - **Capabilities**: 100/100 - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28. ## Install ### How do I install the Agent Margin Router MCP server? Agent Margin Router is a hosted endpoint at https://agent-margin-router-production.up.railway.app/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation. ### Claude ```bash claude mcp add --transport http agentmarginrouter-agent-margin-router 'https://agent-margin-router-production.up.railway.app/mcp' ``` ### Cursor ```json { "mcpServers": { "agentmarginrouter-agent-margin-router": { "url": "https://agent-margin-router-production.up.railway.app/mcp" } } } ``` ### VS Code ```json { "servers": { "agentmarginrouter-agent-margin-router": { "type": "http", "url": "https://agent-margin-router-production.up.railway.app/mcp" } } } ``` ### Codex ```toml [mcp_servers.agentmarginrouter-agent-margin-router] url = "https://agent-margin-router-production.up.railway.app/mcp" ``` ### opencode ```json { "$schema": "https://opencode.ai/config.json", "mcp": { "agentmarginrouter-agent-margin-router": { "type": "remote", "url": "https://agent-margin-router-production.up.railway.app/mcp", "enabled": true } } } ``` ### OpenClaw ```bash openclaw mcp add agentmarginrouter-agent-margin-router --url 'https://agent-margin-router-production.up.railway.app/mcp' --transport streamable-http ``` ### Hermes ```yaml mcp_servers: agentmarginrouter-agent-margin-router: url: "https://agent-margin-router-production.up.railway.app/mcp" ``` ### Netclaw ```json { "McpServers": { "agentmarginrouter-agent-margin-router": { "Transport": "http", "Url": "https://agent-margin-router-production.up.railway.app/mcp" } } } ``` ### Vellum ```bash assistant mcp add agentmarginrouter-agent-margin-router -t streamable-http -u 'https://agent-margin-router-production.up.railway.app/mcp' ``` ### Other ```json { "mcpServers": { "agentmarginrouter-agent-margin-router": { "type": "http", "url": "https://agent-margin-router-production.up.railway.app/mcp" } } } ``` The mcpServers block is a cross-client convention.
