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://preflight.agentdiet.dev/v1/broker/execute)
Output
Returns matched MCP servers and A2A tools relevant to the query, including endpoint metadata, compressed tool manifests (85% token reduction), and safety validation status from the Prompt-Guard firewall. Response schema is a generic object containing ranked tool results.
Example use cases
Discover tools for GitHub security audits
“Find me an MCP server or A2A tool that can run GitHub security audits — search your index and tell me what's available.”
Verify a specific endpoint URL is safe
“Can you check if this endpoint URL is safe and properly indexed: https://some-mcp-server.example.com/v1/execute — verify it through the broker before I connect my agent to it.”
Route agent swarm to context compression
“My agent swarm needs a context compression tool — search the tool index for anything that does token compression or context summarization and give me the best match.”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/broker/execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to discover, validate, or route to any of 500+ MCP or A2A tools through a single connection rather than maintaining separate integrations. Ideal for agent orchestration layers, swarm routers, or any system that dynamically selects tools at runtime. Prefer over direct tool connections when prompt-injection firewall protection and token compression are required.
Side effects
- Empty or overly broad query returns too many or irrelevant results
- Query for a niche capability returns no matches if not yet indexed
- Endpoint URL verification may return false negatives for newly registered endpoints
- Token compression artifacts may alter tool manifest semantics
- Payment failure via x402 prevents execution
