How this service works
Single-connection meta-router indexing 500+ MCP servers & A2A tools with 85% token compression and Prompt-Guard firewall. (Live x402 v2, IETF MPP & MCP endpoint at https://workflows.agentdiet.dev/v1/broker/execute)
Output
Returns a filtered, token-compressed list of matching MCP servers and A2A tools relevant to the query, including metadata about each tool's capabilities, with responses passed through a Prompt-Guard firewall to strip injection attempts.
Example use cases
Finding MCP tools for SEC filings
“Search your index of 500+ MCP servers for any tools that handle SEC filings or EDGAR data — I want a compressed list of what's available so I can pick the best one for my research agent.”
Safe-proxy routing for GitHub audits
“Route my query for 'github security audit' through your swarm router with the prompt firewall on — I need to find the right A2A tool and make sure any responses are sanitized before they hit my pipeline.”
Discovering context compression tools
“Search your MCP tool index for anything related to 'context compression' or token reduction — my agent is running into context window limits and I need to find a suitable tool fast.”
Technical details
Endpoint
POSThttps://workflows.agentdiet.dev/v1/broker/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover which MCP server or A2A tool is best suited for a task at runtime, rather than hardcoding a specific tool. Especially useful when operating in multi-agent swarms where tool availability may vary, when prompt injection protection is required, or when token budget is constrained and 85% compression is needed. Prefer over manual tool registries when the landscape of available tools changes frequently.
Side effects
- Empty query string returns a validation error (minLength:1 not met)
- No matching tools found for obscure or misspelled capability queries
- Prompt-Guard firewall may reject or sanitize queries containing injection-like patterns
- Upstream MCP server unavailability may result in partial or empty result sets
- Rate limiting or payment failure (x402) may block execution
