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://shopify-intel.agentdiet.dev/v1/agent-tool-marketplace)
Output
A compressed, firewall-screened response listing matching MCP servers or A2A tools from a 500+ tool index, including tool metadata, capability descriptions, and routing information — all reduced by approximately 85% in token count compared to raw upstream responses.
Example use cases
Routing agent to best SEC filing tool
“Search the agent tool marketplace for any MCP servers or A2A tools that can pull SEC filings — I need a compressed summary of the best matches so my research agent can connect to one.”
Finding a prompt-safe GitHub auditing tool
“Look up the tool marketplace for a GitHub security auditing capability — I want to make sure the result passes the prompt-injection firewall before my coding agent calls it.”
Discovering DEX token intelligence tools
“Can you query the A2A and MCP tool index for anything that does DEX token intelligence or on-chain risk analysis? Return the top matches with token-compressed metadata.”
Technical details
Endpoint
POSThttps://shopify-intel.agentdiet.dev/v1/agent-tool-marketplace?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to discover the best available MCP server or A2A tool for a specific capability without maintaining direct connections to hundreds of individual endpoints. It is the right choice when token budget is constrained (85% compression), when safety screening of tool responses is required (Prompt-Guard firewall), or when the agent ecosystem needs a single-connection meta-router rather than managing 500+ individual integrations. Prefer it over direct MCP server connections when tool availability is uncertain or when the agent needs to compare multiple tools before committing to one.
Side effects
- No matching tools found for the query — returns empty results or low-confidence matches
- Query string too vague — results may be overly broad or irrelevant
- Upstream MCP server unreachable — proxy reports connectivity failure
- Prompt-Guard firewall blocks a result flagged as containing injection risk
- Payment not completed — HTTP 402 returned if x402 micropayment not settled
- Invalid query input (empty string) — schema validation error
