The previous fix regenerated the MCP config per call but still pulled the tool set from pi.getAllTools(), which depends on the runtime binding being scoped to the right AgentSession. Engine-spawned triage/executor sessions register custom tools (fn_review_spec, fn_review_step) and pi-ai already passes those to the provider via Context.tools — that's the authoritative per-session list and bypasses any binding ambiguity. Falls back to pi.getAllTools() when the caller doesn't populate Context.tools. Also logs the tool names on refresh so missing tools are diagnosable from stderr.

pi-claude-cli
A pi extension that routes LLM calls through the Claude Code CLI as a subprocess. Use your Claude Pro/Max subscription as the LLM backend — no API key, no separate billing.
How it works
The extension registers as a custom pi provider exposing all Claude models. Each request spawns a claude -p subprocess using the stream-json wire protocol, with --resume on follow-up turns to reuse the CLI's session state instead of replaying full history. Claude proposes tool calls, pi executes them natively. Custom pi tools are exposed to Claude via a schema-only MCP server.
Requirements
- Claude Code CLI installed and authenticated (
claudeon PATH) - A Claude Pro or Max subscription
- pi or GSD
Installation
Add to ~/.gsd/agent/settings.json:
{
"packages": ["npm:pi-claude-cli"]
}
Then select a Claude model via /model in the interactive UI. All Claude models appear under the pi-claude-cli provider.
Features
- Streams text, thinking, and tool call tokens in real-time
- Maps tool names and arguments bidirectionally between Claude and pi
- Exposes custom pi tools to Claude via MCP (schema-only, no execution)
- Break-early pattern prevents Claude CLI from auto-executing tools
- Session resume via
--resumeeliminates history replay on follow-up turns - Configurable thinking effort with elevated budgets for Opus models
- Cross-platform subprocess management (Windows, macOS, Linux)
- Inactivity timeout and process registry for cleanup
