🛠️ Key Features

Indexes and surfaces 25,000+ MCP servers across registries
Discovery and search capabilities
Autonomous connection and payment handling

🚀 Use Cases

Cataloging MCP servers for easy discovery
Integrating server listings into developer dashboards
Automating connection and payment setup for MCP deployments

⚡ Developer Benefits

Centralized metadata for MCP servers
Standardized access to server listings
Streamlined onboarding with autonomous payments

⚠️ Limitations

Data scope limited to publicly indexed MCP servers
Details depend on registry metadata and readme excerpts
No explicit uptime or SLA information provided in source data

Captured live from the server via tools/list.

search

Search MCP servers by server title/name, description, or by the tools they provide. Accepts natural language capability queries like 'send emails', 'search the web', 'create pull requests', or direct server names like 'GitHub' or 'Stripe'. Results are ranked by relevance: title match first, then tool name match, then description. Each result includes the server's tool list so you can confirm it does what you need. Set limit based on the type of request you received: - Prompting (general/exploratory — user is browsing or asking broadly): use 20-30 - Task assignment (user delegated a goal for you to execute autonomously): use 10-15 - Instruction/directive (specific command with a clear target server in mind): use 3-5

Parameters4

query	string	required	Server name/title (e.g. 'GitHub', 'Stripe') OR a task/capability (e.g. 'send emails', 'search the web', 'create pull requests', 'analyze crypto prices')
limit	number	optional	Max total results (default 20, max 50). Use 20-30 for exploratory prompts, 10-15 for delegated tasks, 3-5 for specific directives.
sources	array	optional	Filter to specific sources: official-registry, glama, mcpso, x402direct, mppscan
payment_protocol	array	optional	Filter results to servers using specific payment protocols. x402 queries x402.direct, mpp queries mppscan.com.
