Tools & Capabilities Breakdown
Foundersignal MCP Tools (4)
get_discover_data
Query FounderSignal's market intelligence database and return all ranked SaaS opportunities scored by revenue proof, competition density, momentum, and build feasibility. Returns structured JSON. Use this first, then write Market Gap / Why Now / Execution Plan narratives for each idea, then call render_report to produce the final HTML artifact.
render_report
Render the final personalized discovery report as a full HTML document. Pass the ideas array from get_discover_data, each augmented with a narrative object containing marketGap, whyNow, and executionPlan (written by you based on the data). Returns an HTML artifact to display directly.
market_query
Query aggregated market intelligence from TrustMRR, AppSumo, Product Hunt, Indie Hackers, Reddit and Google SERP. Returns a ranked text table of SaaS opportunities scored across revenue proof, momentum, entry window, pain intensity and build feasibility.
generate_report
Generate a full HTML market intelligence report with all ranked opportunities.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Foundersignal MCP is categorized under Aggregators and uses a local stdio subprocess. In contrast, Orcarouter MCP Server belongs to Aggregators using local stdio subprocess. Select Foundersignal MCP when you need capabilities focused on aggregators and Orcarouter MCP Server when you require tools for aggregators.
Send a single-turn chat request to OrcaRouter and return the assistant's response text. Default model is the workspace's auto-router. Use `orcarouter/<name>` for other routers or `<provider>/<model>` for direct calls. For OpenAI reasoning models (gpt-5/o1/o3/...), max_tokens is automatically routed to max_completion_tokens at the wire level. The optional `models` array sets a fallback chain — the primary `model` is tried first, then each entry on failure (5 entries total max, including the primary). Errors are returned as text content with isError:true; common cases include missing API key, rate limits, and upstream provider outages. Requires ORCAROUTER_API_KEY.
orcarouter_models_list
List LLM models in the OrcaRouter catalog. Each entry includes id, name, description, owned_by, context_length, supported_endpoint_types, and pricing (both per-token and per-million tokens). Filter by `provider`, `capability`, or `min_context` — filters compose (all conditions must match) and are applied server-side. Discover valid provider ids first with orcarouter_providers_list. Returns the full catalog when called without filters. Read-only, no API key required.
orcarouter_model_card
Get detailed information about a single model — display name, long description, pricing (per-call and per-million tokens), context window, max output, modalities (input/output), supported endpoints, latency percentiles (p50/p95), and release date. Use this when you already know the model id and want full details; for browsing or filtering across many models use orcarouter_models_list instead. Returns isError:true with a clear hint when the id is not found. Read-only, no API key required.
orcarouter_providers_list
List all model providers on OrcaRouter with their `provider_id`, human-readable `display_name`, `icon_url`, and `model_count`. Call this first to discover valid provider ids (e.g. 'openai', 'anthropic', 'google', 'qwen', 'deepseek') which you can then pass to orcarouter_models_list as the `provider` filter. Takes no parameters and returns the same list on every call until the deployment's catalog changes. Read-only, no API key required.
