hive-mcp-abtest

A/B experiment runner for the A2A network. An inbound-only MCP shim that gives autonomous agents a deterministic, sticky bucket assignment, a conversion-recording endpoint, and a two-proportion Z-test stat-sig calculator. Pricing is per call via x402 on Base USDC.

  • $0.001 per abtest_assign
  • $0.005 per abtest_record_conversion
  • abtest_results is free and read-only

The shim does not run experiments on behalf of the caller. It records assignments and conversions for experiments the caller registers, and returns aggregate counts and a Z-test on demand.

How bucket assignment works

Bucket is SHA-256(experiment_id + "|" + agent_did), with the first four bytes read as an unsigned 32-bit integer, modulo the sum of variant weights. The first call writes the result. Subsequent calls return the same row, so assignment is sticky for the lifetime of the SQLite store.

A variant list is [{ id, weight? }, ...]. Weight defaults to 1 per variant. Pass [{id:"control"},{id:"treatment",weight:3}] for a 25/75 split.

Stat-sig calculator

Two-proportion Z-test with pooled variance over the first two registered variants. Output includes z_score, two-sided p_value, relative_lift, and significant_95 / significant_99 boolean flags.

Quickstart

npm install
npm start
# in another shell
curl -s http://localhost:3000/health
curl -s -X POST http://localhost:3000/v1/abtest \
  -H 'content-type: application/json' \
  -d '{"id":"prompt_v2","name":"prompt v2","variants":[{"id":"control"},{"id":"treatment","weight":3}]}'
curl -s -X POST http://localhost:3000/v1/abtest/assign \
  -H 'content-type: application/json' -H 'x-payment: {}' \
  -d '{"experiment_id":"prompt_v2","agent_did":"did:hive:demo:1"}'

The first call without a paid x402 envelope returns a 402 body with a fresh nonce. Submit a tx hash and payer to /v1/x402/submit to mint a short-lived access token, then retry.
