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/workflows/execute)
Output
Returns a token-compressed list of matching MCP servers and A2A tools from a 500+ entry index, including capability metadata, filtered through a Prompt-Guard firewall to prevent prompt injection from untrusted tool responses.
Example use cases
Routing agent to SEC filing tool
“I'm building an autonomous research agent and need to find which MCP servers in your index support SEC filings or EDGAR data — can you search for that and give me the best match?”
Discovering context compression tools
“Search the MCP tool index for anything related to 'context compression' — I want to reduce token usage in my agent pipeline and need to find the right server to connect to.”
Finding GitHub security audit agents
“Which A2A tools or MCP servers in your directory handle GitHub security audits? Search for 'github security' and return the top matches so I can wire them into my swarm.”
Technical details
Endpoint
GEThttps://workflows.agentdiet.dev/v1/workflows/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover which MCP servers or A2A tools are available for a given capability without maintaining your own registry, especially when token efficiency matters (85% compression) or when you need a single connection that routes across 500+ tools with built-in prompt injection protection.
Side effects
- Missing or empty 'query' parameter returns a 400 error
- No matching tools found for the query returns an empty result set
- Payment not processed via x402 returns 402 Payment Required
- Firewall blocks a result flagged as prompt injection attempt
- Upstream MCP server index unavailable causes degraded or empty results
