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/swarm-execute)
Output
Returns a compressed, token-pruned list of matching MCP servers or A2A tools relevant to the query, including endpoint metadata, capability descriptions, and safety/firewall status, structured as a JSON object.
Example use cases
Discovering MCP tools for security auditing
“Search the tool index for any MCP servers or A2A agents that handle GitHub security audits or code vulnerability scanning — I need to find something I can route my repo analysis through.”
Finding context compression agents
“Look up what tools are available in the swarm router for context compression or token reduction — I'm hitting token limits in my pipeline and want to see if there's an indexed MCP server that can help.”
Verifying a specific endpoint before use
“Can you check whether this endpoint URL is indexed and verified in the swarm router: https://some-mcp-server.example.com/v1/tool — I want to make sure it's safe to call before routing agent traffic to it.”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/swarm-execute?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to dynamically discover the right MCP server or A2A tool from a large index without maintaining its own tool registry. It is particularly valuable when you want a single connection point to 500+ tools with built-in safety filtering and token-efficient responses, rather than querying individual tool registries or maintaining a hardcoded tool list.
Side effects
- Empty or too-vague query returns no matches or overly broad results
- Unknown or unindexed endpoint URL returns null verification result
- Prompt-Guard firewall blocks queries that contain injection patterns
- Service unavailable if the meta-router index is being updated
- Rate limiting or payment failure (x402) if quota exceeded
