XPI

Security tools for Pi Agent: casefile tracking, web search, library docs, exploit technique search, code intelligence, and todos.

Install

Automate XPI plus third-party extension deps (pi-codex-goal, pi-mcp-adapter):

./install.sh

Or:

pi install npm:@xaccefy/pi-xpi

API keys / env

Variable	Package	Purpose
PREVIEW_IS_API_KEY	exploitsearch	Required for ExploitSearch (preview.is)
PI_XP_MODE	casefile	on / off — force casefile cyber-workflow injection
PI_CASEFILE_PATH	casefile	Override SQLite ledger path
PI_WEBSEARCH_PORT	lookup	open-websearch daemon port (default 3210)
PI_CHROMIUM_PATH	lookup	Chromium binary for SPA re-render in web_fetch

export PREVIEW_IS_API_KEY="rk_yourkeyhere"

Tools

Tool	Use for
auth / /auth	Hold & use login sessions for targets (cookie, OAuth client-credentials, mTLS); engage signup/login to make a temp account on its own + prove it
ExploitSearch	Attack techniques, primitives, bypasses (PREVIEW_IS_API_KEY)
web_search	CVEs, advisories, documentation
web_fetch	Page content; SPA pages re-rendered via Chromium when the shell is thin
context7	Current library docs
deepwiki	Q&A on a public GitHub repo
CaseAdd / CaseUpdate / PromoteFinding	Ledger + hard PoC gate to confirm
CaseGet / CaseList / CaseSearch	Browse cases
CaseLink / CaseUnlink	Exploit chains
CaseReport	Markdown report
/casefile	Case dashboard
/xp	Toggle casefile XP mode (cyber workflow injection; default OFF)
todo / /todos	Multi-step task lists
codebase-memory-mcp	Polyglot code indexer (158 languages). Tools: index_repository, search_graph, trace_path, get_architecture, query_graph. Installed by install.sh as an MCP server.

Quick start

/ops <bugbounty|ctf|pentest> <target>   # start an engagement
/pipeline <audit|harness|patch> <target>   # VDH/VVS discovery→validate→patch
/xp on                                      # enable casefile cyber workflow in context

Engagements and pipelines restate the workflow in the prompt body, so they work with XP mode off. Use /xp on when you want the full attacker discipline injected every turn.

Code intelligence (codebase-memory-mcp)

XPI uses codebase-memory-mcp as its default code indexer. It's a single static binary that indexes 158 languages via tree-sitter plus a Hybrid LSP type-resolution layer, exposing 14 MCP tools (index_repository, search_graph, trace_path, get_architecture, query_graph, get_code_snippet, …).

install.sh installs it as an MCP server alongside the in-process XPI extensions. For a readable target repo, index once with index_repository, then get_architecture for layout and trace_path to prove source→sink reachability — across Go, Solidity, Python, Rust, TS/JS, and 150+ others.

The previous in-process @xaccefy/pi-codeintel package (TS/JS-only, TypeScript-compiler-based) was removed in favor of this polyglot backend. The agent falls back to grep/read when no indexer is available.

Develop / release

bun install
bun test --isolate
bun run typecheck

Release (CI): GitHub Actions → Release workflow → choose patch / minor / major.
Requires repo secret NPM_TOKEN. The job runs tests, bumps all workspace versions, publishes every package + umbrella, tags vX.Y.Z, and pushes.

Local release helper:

bun run release:patch   # or release:minor / release:major

(Requires a clean tree, npm auth, and push rights.)
