The full upstream README, mirrored here for reference. Install config, tool schemas, adoption signals, and an original overview live on the Singularity MCP Discovery & Security Gateway listing page.
Perplexity for MCP. Discover the right tool for a problem, see its trust card (prompt-injection risk, permission overreach, publisher status), connect it in one click, and execute it through a secure, audited gateway — one product, one config.
See ROADMAP.md for the full plan. Blueprint: ../Singularity_Blueprint.md.
A fresh boot with an empty database auto-seeds itself — seed_index.py is only needed
for manual re-seeding.
Singularity is a native MCP server (streamable HTTP, stateless) at /mcp.

Then just ask your agent: "my team needs expense tracking" — it calls find_solutions
and gets ranked options with trust cards and security flags.

| Tool | What it does |
|---|---|
find_solutions(problem, top_k?, max_pricing_tier?) | Ranked, trust-scored recommendations with plain-language security flags |
get_trust_report(slug) | Full security card: permissions requested vs needed, injection-scan verdicts, publisher status |
compare_tools(slugs[]) | Side-by-side trust table for shortlisted candidates |
Every result carries fit_score, trust_score, rank_score, trust_flags, and a
human-readable rationale. The seed index includes quickledger-pro, an intentionally
poisoned fictional tool — ask about expenses and watch it get flagged
(suspicious_description_imperative, hidden_unicode_characters, permission_overreach)
and pushed down the ranking.
