@gitdealflow/mcp-signal — Startup Engineering Velocity Signals for AI Agents

MCP server for searching, shortlisting, comparing, and predicting startup engineering acceleration across 15 sectors. Tracks commit velocity, contributor growth, and repository expansion for 350+ GitHub orgs. Built for VCs, angels, scouts, and technical operators who need transparent, citable deal-flow signals before they show up in traditional channels.

One-click install for Claude Desktop / Cursor / Cline / Continue via Smithery — verified, 98/100 quality score.

Use Cases

Who	How they use it
VCs & Angel Investors	Screen Crunchbase profiles against live engineering velocity data. Use predict_funding for transparent, citable funding-likelihood scores with full evidence chains.
Startup Founders	Benchmark your own engineering velocity against 350+ tracked startups across your sector. Identify acquisition targets or partnership opportunities.
Recruiters & Hiring Teams	Find startups with accelerating engineering teams — the teams that are building fast and hiring.
Scouts & Syndicate Leads	Run shortlist_signals with sector/geography filters to surface the strongest deals in your thesis area. Use get_scout_receipts to validate your pattern recognition against 75+ unicorns.
Corp Dev & M&A Teams	Monitor competitor velocity trends and identify breakout acquisition targets 3–6 weeks before fundraise announcements.
AI Agents & Copilots	Integrate startup signals into agentic workflows — deal sourcing, company research, portfolio monitoring, and investment thesis generation.

Tools

All tools are read-only, idempotent, and fetch live data from the public API (no auth required). Responses include both human-readable text and structured JSON (structuredContent) matching each tool's outputSchema.

Tool	Input	Returns
get_trending_startups	—	Top 20 startups ranked by engineering acceleration across all sectors.
search_startups_by_sector	sector (enum of active slugs — currently 15)	All tracked startups in the sector, ranked by acceleration.
get_startup_signal	name (case-insensitive)	Full signal profile for one startup: velocity, contributors, repos, classification.
get_signals_summary	—	Dataset snapshot — period, counts, refresh date, format URLs, citation.
get_methodology	—	How signals are sourced, computed, and classified, with known limitations.
predict_funding	name	Transparent, scored funding-likelihood claim for one startup — score, full evidence chain, confidence, caveats, and methodology + SSRN provenance so the number is citable, not opaque.
compare_signals	names (2–5)	Head-to-head scored comparison of named startups, ranked, with a diligence recommendation.
shortlist_signals	sector?, geography?, signalType?, minAccelerationScore?, minVelocityChangePct?, limit?	The whole sourcing workflow in one call — "5 strongest signals in healthcare in the EU", ranked by acceleration score with a rationale each.
get_diligence_dossier	name	Public-source diligence dossier for one company in a cited object — M&A history (acquirer, year, amount), funds that publicly backed it, and the published engineering-acceleration signal.
get_scout_receipts	github_username	Scout Score (0–100) for a GitHub user from their public starring history vs. validated unicorns.

Provenance, not opaque numbers. predict_funding, shortlist_signals, and compare_signals use one transparent, deterministic scoring engine (velocity ≤40 + contributor-growth ≤25 + new-repos ≤15 + signal-class ≤20 = 0–100). Every input and weight is returned in the response so a downstream agent can audit and cite the score. Geography is region-level only (US/EU/UK/APAC/LATAM/Canada); city/country aliases normalize up to the region. These are heuristics over public GitHub activity — not investment advice and not a guarantee of any financing event.

Three paid agent tools (research_company, compose_thesis, deep_dive_scan) add enriched dossiers, thesis scaffolds, and multi-cohort sector scans for API-key holders — see /pricing.

Supported sectors (active, refreshed weekly): healthcare, edtech, ecommerce-infrastructure, supply-chain, web3, enterprise-saas, data-infrastructure, robotics, legal-tech, hr-tech, proptech, agtech, gaming, space-tech, social-community.
