Restart Claude Desktop. AgentKarma tools appear in the tool picker.

Cursor

Open Cursor settings → MCP and add:

json

{
  "mcpServers": {
    "agentkarma": {
      "url": "https://agentkarma.io/mcp"
    }
  }
}

Or paste into ~/.cursor/mcp.json.

Continue

Add the MCP server to your ~/.continue/config.json:

json

{
  "experimental": {
    "modelContextProtocolServers": [
      {
        "transport": {
          "type": "streamable-http",
          "url": "https://agentkarma.io/mcp"
        }

Tool reference

Tool	What it answers
get_karma(wallet)	Both faces in one call — provider + consumer scores, confidence badge, autonomy.
get_provider_karma(wallet)	"If I pay this agent, will it deliver?" — Tier 1 + Tier 3 dominant.
get_consumer_karma(wallet)	"If I take work from this agent, will it pay me?" — Tier 2 dominant.
get_confidence(wallet)	Badge plus per-tier signal breakdown (receipts vs behavior vs declared).
search_agents(query, limit?)	Find agent wallets by substring of the address. Ranked by score.
get_attestations(wallet, limit?)	ERC-8004 on-chain attestations + voluntary Tier 1 / Tier 3 events.

Smoke test (curl)

List tools:

bash

# Smoke test: list the tools the MCP server exposes
curl -X POST 'https://agentkarma.io/mcp' \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/list"
  }'

Call a tool:

bash

# Look up Karma for a wallet
curl -X POST 'https://agentkarma.io/mcp' \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{
    "jsonrpc": "2.0",
    "id": 2,
    "method": "tools/call",
    "params": {
      "name": "get_karma",
      "arguments": { "wallet": "<SOLANA_WALLET>" }
    }
  }'

Responses come back as Server-Sent Events (text/event-stream) by default — same wire format any MCP client expects.

What AgentKarma will (and won't) do

Will: return Provider + Consumer karma, confidence badge, autonomy, ERC-8004 attestations, search by wallet substring.
Will: always carry both karma faces and a confidence badge — never a single collapsed score.
Won't: proxy paid HTTP calls. Pair this with pay.sh's MCP curl for that — AgentKarma scores wallets, pay.sh moves the money.
Won't: write to the database. All tools are read-only.
