Nexus
Connect your AI coding agent to third-party tools through Civic Nexus—a zero-setup MCP gateway with authentication and workflows instead of wiring each integration yourself.
Overview
Civic Nexus is an MCP server for the Build phase that acts as a zero-setup authenticated gateway connecting AI clients to external tools and workflows over streamable HTTP.
What is this MCP server?
- Zero-setup MCP gateway hosted at nexus.civic.com/hub/mcp
- Streamable HTTP remote — no local server required to start
- Authentication layer for connecting AI to external tools
- Workflow support on top of raw tool calls
- Open-source hub in github.com/civicteam/civic-mcp (apps/hub), catalog version 0.1.99
- Server version 0.1.99
- Remote URL: nexus.civic.com/hub/mcp
- Hub source: civicteam/civic-mcp apps/hub on GitHub
What problem does it solve?
Indie builders waste time duplicating OAuth flows and MCP wiring for every tool their agent must call securely.
Who is it for?
Solo developers assembling multi-tool agent products who need a single secured MCP entry point during active integration work.
Skip if: Builders who only need one static, self-hosted stdio MCP with no auth requirements or workflow routing.
What do I get? / Deliverables
You point your agent at one Nexus hub URL and gain a managed MCP gateway with authentication and workflows instead of many fragile integrations.
- Authenticated MCP path from agent to connected tools
- Workflow-capable tool calls without a custom gateway codebase
Recommended MCP Servers
Journey fit
MCP gateways sit squarely in Build when you are wiring the agent stack to external services and need a secure hub rather than one-off scripts. Integrations is the canonical shelf because Nexus is explicitly a gateway that links MCP clients to tools with auth and workflow orchestration.
How it compares
Central MCP gateway with auth, not a single-domain API skill or a raw OAuth library.
Common Questions / FAQ
Who is Civic Nexus for?
Developers shipping MCP-based agents who want Civic to host authentication and tool routing so they do not maintain a separate gateway service.
When should I use Civic Nexus?
Use it in Build while connecting your agent to multiple external tools and you need authenticated, workflow-aware MCP access without standing up your own hub.
How do I add Civic Nexus to my agent?
Add the remote MCP server https://nexus.civic.com/hub/mcp (streamable HTTP) in your client config and complete Civic’s authentication flow as documented on nexus.civic.com.
