Any MCP client

npx shibbo mcp

Starts a stdio MCP server. Most clients take the same entry:

{ "mcpServers": { "shibbo": { "command": "npx", "args": ["shibbo", "mcp"] } } }

The tools are listed in the MCP reference.

Getting the agent to use it

An MCP tool only helps if the agent calls it. Add this line to your instructions file (shibbo export and shibbo init add it for you):

After writing prose a person will read (docs, READMEs, PR text, UI copy), call the shibbo
check_text tool or run `npx shibbo check <file>`, and fix what it reports.

Agents follow this well for documents and less reliably for short chat replies. Where your harness has hooks, prefer them, since a hook runs every time.
