Tools & Capabilities Breakdown

Sieve MCP Tools (8)

sieve_screen

Run a Sieve IMPACT-X Quick Screen on a startup. Analyzes the company across 7 dimensions (Innovators, Market, Product, Advantage, Commerce, Traction, X-Factor) and returns an analysis ID. Takes 2-5 minutes to complete. Upserts -- if the company was previously screened, returns the existing deal (set confirm=true to re-screen). Two ways to use: - v3 (recommended): First add documents with sieve_dataroom_add, then call sieve_screen(deal_id=...) to analyze everything in the data room. - v2 (legacy): Call sieve_screen(company_name=..., website_url=...) directly. At least one of website_url or pitch_deck_text is required in this mode.

sieve_status

Check the progress of a Sieve analysis. Returns which IMPACT-X dimensions are complete with their scores, overall progress percentage, and current phase.

sieve_results

Get the full results of a completed Sieve analysis. Returns the Sieve Score (0-140), meeting decision (Take Meeting/Pass/ Need More Info), executive summary, key strengths, and key concerns.

sieve_usage

Check your Sieve API usage for the current billing period. Shows screens used, monthly limit, tier, and organization name.
