AgentsIndex MCP server

Which MCP servers are AgentsIndex's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Addresshttps://agentsindex.ai/mcpnot in the official registry: answered when asked

No entry in the official MCP registry names this server. It answered on agentsindex.ai when the Atlas asked at the address servers are usually mounted on, so it is the vendor's own. Clients and catalogues that list servers from the registry do not show it.

When we asked itchecked 2026-10-28
  • Stateanswerschecked 2026-10-28
  • Server calls itselfai.agentsindex/mcp
  • Server version1.0.0
  • Protocol version2025-06-18

On 2026-10-28 the server answered initialize and tools/list without a sign-in. First answer in 347 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: compare AI agent tools within one category; submit a tool to get it listed.
  • Checked on 5 of the 7 days it takes to judge reliability.

Once connected

  • For "compare AI agent tools within one category", the likely first call is get_best_of.
  • For "submit a tool to get it listed", the likely first call is submit_listing.
  • Keep approval on for send_lead: they delete, send or pay without saying so.
  • send_lead, create_order change data without a sign-in: anyone with the address can call them.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

  • Tools that delete, send or pay, marked as not destructive: send_lead
  • Tools that change data, on a server that answers without a sign-in: send_lead, create_order

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "agentsindex": {
      "type": "http",
      "url": "https://agentsindex.ai/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http agentsindex https://agentsindex.ai/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://agentsindex.ai/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
