Available MCP Tools (9)

Every tool your AI coding assistant needs to validate ideas, extract customer signals, and prevent scope creep.

Market Scanning

query (string, required), projectId (string, optional)

Response

{ startups: [{ name: 'InspectAI', batch: 'W24', status: 'Active', description: '...' }] }

Execution Intelligence

ideasignal_get_mvp_blueprint

Get the forensic 7-day MVP execution blueprint (Must-Build core features, Defer features, and NEVER-build scope) to keep AI coding agents grounded.

Inputs

projectId (string, required)

Response

{ mustBuild: ['Core wedge loop', 'Auth'], defer: ['Team seats', 'Billing portal'], neverBuild: ['Dark mode theme engine'] }

AI Coding Spec

ideasignal_generate_ai_spec

Generate an exhaustive, production-grade SPEC.md technical blueprint (database schema, API contracts, user state transitions) tailored for Cursor and Claude Code.

Inputs

projectId (string, required), techStack (string, optional)

Response

{ spec: '# SPEC.md\n## 1. Database Schema\n...' }

Ground Truth

ideasignal_get_real_user_evidence

Retrieve exact verbatim quotes, sentiment scores, and pain points extracted from Reddit threads and X discussions for a project.

Inputs

projectId (string, required), category (string, optional)

Response

{ evidence: [{ source: 'Reddit (r/SaaS)', text: 'I am so tired of manual CSV imports...', sentiment: 0.21 }] }

Audience Profiling

ideasignal_generate_icp_persona

Extract forensic customer persona with daily pain points, buying triggers, budget authority, and exact online watering holes (subreddits/discords).

Inputs

problem (string, required), audience (string, required), solution (string, optional)

Response

{ personaName: 'DevOps Lead Dan', wateringHoles: ['r/devops', 'Kubernetes Slack'], buyingTriggers: ['CI build timeout spikes'] }

Workspace

ideasignal_list_projects

List all startup ideas and validated projects in the user's workspace with validation scores and GO/PIVOT/KILL verdicts.

Inputs

None

Response

{ projects: [{ id: 'proj_123', name: 'DevTool AI', score: 84, verdict: 'GO' }] }

Workspace

ideasignal_get_project_brief

Get the complete idea brief (Problem, Target Audience, Solution, Vision, Hypotheses, Viability Score, and Verdict) for a specific project.

Inputs

projectId (string, required)

Response

{ project: { name: 'DevTool AI', workspace: { problem: '...', audience: '...' }, verdict: 'GO' } }
