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://mcp-security.agentdiet.dev/v1/workflows/code-release-security-gate)
Output
Returns a compressed list of matching MCP servers or A2A tools relevant to the query, including endpoint metadata, capability descriptions, and safety-filtered results, with up to 85% token reduction compared to raw tool manifests.
Example use cases
Discovering tools for SEC filing access
“Search the MCP tool index for any servers or A2A agents that can retrieve SEC filings or EDGAR company data, and give me a compressed summary of what's available.”
Finding a prompt-safe web distillation tool
“I need to find an MCP server that handles web URL distillation or HTML summarization — search the index and make sure the result passes the prompt-guard firewall before you send it back.”
Routing agent query to company enrichment tools
“Look up what MCP or A2A tools are available for B2B lead enrichment or company data enrichment, and tell me which one is the best match for my use case.”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/workflows/code-release-security-gate?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to dynamically discover available MCP servers or A2A tools at runtime without hardcoding individual tool URLs. Ideal for swarm orchestration scenarios where the agent must find the best capability for a given task from a large index, especially when token budget is constrained (85% compression) or when prompt-injection safety is a concern.
Side effects
- Empty results if the query is too niche or no indexed tools match
- Prompt-Guard firewall may block or sanitize queries containing injection patterns
- HTTP 402 payment required if x402 credentials are missing or invalid
- Timeout if the meta-router cannot reach indexed MCP backends within SLA
- Malformed query (missing required 'query' field) returns validation error
