MCP Servers
The Model Context Protocol (MCP) lets RedCell call tools hosted by external servers — scanners, knowledge bases, or your own scripts. RedCell starts each configured server, lists its tools, and makes them available to the agent during a session.
Configure a Server
Add servers under [mcp_servers] in config.toml. Each entry names a command RedCell runs to launch the server over stdio:
config.toml
[mcp_servers.example]
command = "npx"
args = ["-y", "@example/mcp-server"]
env = optional key/value pairs
Using Tools
Once a server is configured, its tools appear to the agent automatically. Tool calls go through the same approval flow as any other action, so you stay in control of what runs.
