pi-search

Free web research for pi that works out of the box. Install it once, ask a question, and pi can search the web, read pages, or find papers with no provider setup or API key.

pi-search is a compact pi extension for finding current material without flooding an agent's context window. After installation, it needs no provider configuration or API key. It combines hosted Exa and Parallel MCP services, returns answer-ready excerpts first, and lets pi fetch source pages only when the details matter.

Why pi-search?

• Works immediately, for free. Install one package and pi is ready to search. Exa and Parallel both offer API-key-free access; add a key only when you need higher rate limits.

• Keep research focused. Search results are excerpt-first, so pi can answer from the useful parts before reading a full page.

• Go beyond general search. Find research papers, preprints, and journal articles through Exa's publication index.

• Stay model-agnostic. The same tools work with any model you run through pi.

pi install npm:@blessium/pi-search

Try it once without installing:

pi -e npm:@blessium/pi-search

Install a local checkout:

pi install /path/to/pi-search

Ask pi

The extension registers its tools automatically. Ask pi for research in natural language:

Describe the ideal source rather than listing bare keywords. Start with web_search, then use web_fetch only for exact wording, a full-page analysis, or conflicting excerpts.

Tools at a glance

For broad questions, pi can send two or three concise search angles to Parallel. For complex research, the advanced and paper tools support type: "deep"; for breaking news, maxAgeHours: 0 forces a live crawl.

Providers and configuration

web_search and web_fetch choose Exa or Parallel deterministically for each pi session, so a conversation stays with one backend. Pin the basic tools to one provider when you need to:

PI_SEARCH_PROVIDER=exa pi
PI_SEARCH_PROVIDER=parallel pi

web_search_advanced and search_papers always use Exa because Parallel does not offer the equivalent filters or publication index.

Both providers have a free tier. Optional keys raise rate limits:

EXA_API_KEY=your-key pi
PARALLEL_API_KEY=your-key pi

Some controls are provider-specific. Parallel honors web_search.queries plus web_fetch.objective and web_fetch.fullContent; Exa searches query alone and uses maxCharacters to cap fetch output. Unsupported controls are safely ignored.

Privacy and security

Each tool call sends its query or URL to the selected Exa or Parallel service over HTTPS. Parallel's basic tools also receive the current pi session ID and active model name. The extension makes no filesystem writes, runs no shell commands, and stores no credentials locally. An optional EXA_API_KEY or PARALLEL_API_KEY is sent only to its matching provider.
