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://serp-extract.agentdiet.dev/v1/bundle-execute)
Output
Returns a token-compressed (up to 85% reduction) list of matching MCP servers or A2A tools from a 500+ endpoint index, with capability metadata, compliance signals, and prompt-injection firewall status applied to results.
Example use cases
Agent swarm capability routing
“I'm building a multi-agent swarm and need to find which MCP servers handle GitHub security auditing and on-chain risk analysis — can you search the tool index and give me the best matches?”
Safe tool discovery for prompt firewall
“Find me any A2A or MCP tools related to prompt injection detection and firewall capabilities so I can plug them into my pipeline safely.”
Endpoint URL compliance check
“I have this MCP endpoint URL I want to use — can you verify it against the index to confirm it's compliant and not flagged for anything?”
Technical details
Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/bundle-execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to dynamically discover, route to, or validate MCP/A2A tools at runtime rather than hardcoding tool references. Particularly useful for swarm orchestrators, meta-agents, or pipelines that need token-efficient tool lookup with built-in prompt-injection protection.
Side effects
- Empty or overly generic query returns too many low-relevance results
- Unknown or misspelled capability terms yield no matches
- Endpoint URL verification fails if URL is not in index
- Rate limiting or payment failure (x402) blocks the request
- Firewall false-positives may suppress valid tool results
