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://prompt-guard.agentdiet.dev/v1/mesh/dispatch)
Output
A filtered, token-compressed response identifying matching MCP servers or A2A tools for the given capability query, routed through a prompt-injection firewall; returns tool metadata, matched endpoints, and proxied results from the best-fit service
Example use cases
Discovering GitHub security audit tools
“I need to find an available MCP tool for auditing GitHub repositories for security vulnerabilities — search across all indexed agent tools and route me to the best one.”
Finding context compression capability
“Can you search for any MCP server or A2A tool that offers context compression or token reduction? I want to reduce my agent's token usage.”
Routing a DEX token intelligence query
“Search across your indexed MCP tools for something that handles DEX token intelligence or on-chain risk analysis, and dispatch my query through it.”
Technical details
Endpoint
GEThttps://prompt-guard.agentdiet.dev/v1/mesh/dispatch?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to dynamically discover and route to one of hundreds of MCP or A2A tools without managing individual connections, especially when token budget is limited and prompt security (injection firewall) is a concern. Prefer over direct MCP server connections when the target tool is unknown or when a single safe proxy point is needed for a swarm of agents.
Side effects
- No matching MCP server or A2A tool found for the query
- Query blocked by Prompt-Guard firewall due to injection attempt
- HTTP 402 payment required if payment not satisfied
- Timeout or upstream MCP server unavailability
- Malformed query returns validation error
- Token compression failure for unusually large responses
