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://onchain-risk.agentdiet.dev/v1/a2a-mesh)
Output
Returns a list of matching MCP servers or A2A tool endpoints indexed by capability, including their metadata, endpoint URLs, and routing information, with token-compressed payloads and prompt-injection firewall screening applied.
Example use cases
Discover SEC filings tool for agent
“Search the A2A mesh for any available tools that can retrieve or analyze SEC filings — I want to connect my research agent to one of those endpoints.”
Find GitHub security audit capability
“Can you query the tool discovery mesh for MCP servers that handle GitHub security audits or code vulnerability scanning?”
Locate context compression service
“I need my agent to find an MCP endpoint that does context or token compression — search the mesh for anything matching 'context compression'.”
Technical details
Endpoint
POSThttps://onchain-risk.agentdiet.dev/v1/a2a-mesh?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover and route to the right MCP server or A2A tool from a large index without maintaining separate connections to each service. Ideal when the target capability is not known in advance and requires real-time search across 500+ tools, especially when token budget is constrained (85% compression) or when prompt-injection safety is required for untrusted tool responses.
Side effects
- Query too vague returns too many unrelated results
- No matching tools found for a niche capability
- Prompt-Guard firewall blocks query if it resembles an injection attempt
- Payment required (HTTP 402) if x402 credit is not pre-authorized
- Downstream MCP server unavailable, causing partial results
- Idempotency-Key collision if reused across different queries
