Which MCP Server Should You Choose?
Choose Claude Task Master when:
You need dedicated capabilities in the Developer Tools domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (BYOK (Pay Provider Direct)).
You have access to required keys: ANTHROPIC_API_KEY, OPENAI_API_KEY, GOOGLE_API_KEY, PERPLEXITY_API_KEY, XAI_API_KEY, OPENROUTER_API_KEY, MISTRAL_API_KEY, TASK_MASTER_TOOLS.
AI-powered task management system for AI-driven development. Features PRD parsing, task expansion, multi-provider support (Claude, OpenAI, Gemini, Perplexity, xAI), and selective tool loading for optimized context usage.
GWAS Catalog (EBI/NHGRI) MCP — curated catalog of genome-wide association studies.
GWAS Catalog: look up a single-nucleotide polymorphism (SNP) by rsID. Returns functional class, chromosome/region locations, and mapped genes (with up/downstream + distance). Keyless, from EBI/NHGRI.
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).
Claude Task Master is categorized under Developer Tools and uses a local stdio subprocess. In contrast, Gwas Catalog belongs to Developer Tools using local stdio subprocess. Select Claude Task Master when you need capabilities focused on developer tools and Gwas Catalog when you require tools for developer tools.
GWAS Catalog: get trait/disease associations for a SNP (rsID) — risk allele, p-value, odds ratio per copy, beta/effect size, and risk allele frequency. Keyless, from EBI/NHGRI.
studies_by_trait
GWAS Catalog: find genome-wide association studies for a disease/trait (EFO trait, e.g. "asthma" or "type 2 diabetes"). Returns accession, PubMed ID, title, journal, date, sample size. Keyless, from EBI/NHGRI.
