Inbound structured-log ingestion shim โ€” Hive Civilization

NDJSON log ingestion at $0.0001/line via x402. Retention tiers (1d free, 7d $0.005/MB, 30d $0.02/MB). Tail + search endpoints. Pure protocol โ€” inbound only, no outbound calls.

Council provenance: Tier A inbound metering shim. Companion to hive-mcp-auction and hive-mcp-barter.


What this is

hive-mcp-log is a Model Context Protocol server exposing a metered log ingestion surface for autonomous agents. Agents POST structured logs (NDJSON) and pay $0.0001/line in USDC on Base L2. They read their own logs back via tail/search at Tier 0 (free). Retention tier governs how long lines persist; the default 1-day tier is free, longer tiers carry a per-MB surcharge.

  • Protocol: MCP 2024-11-05 over Streamable-HTTP / JSON-RPC 2.0
  • Transport: POST /mcp
  • Discovery: GET /.well-known/mcp.json
  • Health: GET /health
  • Settlement: USDC on Base L2 โ€” real rails, no mock, no simulated
  • Brand gold: Pantone 1245 C / #C08D23
  • Inbound only: the service never reaches out, never DMs, never pulls

GET /health Service health.

Pricing

Ingest:    $0.0001 per log line
Retention:
  1d   (default)   free
  7d               $0.005 / MB

NDJSON ingest example

curl -X POST https://hive-mcp-log.onrender.com/v1/log/ingest \
  -H 'content-type: application/json' \
  -H 'x-hive-did: did:hive:agent-foo' \
  -d '{
    "did": "did:hive:agent-foo",
    "retention_class": "7d",
    "lines": [
      { "ts": "2026-04-27T20:00:00Z", "severity": "info",  "tag": "tool", "msg": "tool_call ok" },
      { "ts": "2026-04-27T20:00:01Z", "severity": "error", "tag": "llm",  "msg": "rate_limited" }
    ]
  }'

The first call returns a 402 with the payment envelope (Base L2 USDC). Settle, then resend with x-hive-tx: <hash> for synchronous verification.

Tail / search example

curl 'https://hive-mcp-log.onrender.com/v1/log/tail?did=did:hive:agent-foo&n=20'
curl 'https://hive-mcp-log.onrender.com/v1/log/search?did=did:hive:agent-foo&severity=error&q=rate'

Retention

curl -X PATCH https://hive-mcp-log.onrender.com/v1/log/retention \
  -H 'content-type: application/json' \
  -d '{ "did": "did:hive:agent-foo", "tier": "7d" }'

A periodic sweep (default hourly) prunes lines older than each DID's retention window.

Security & scope

  • Cross-DID reads are not exposed in v1 (own-DID only via tail/search).
  • No PII detection in v1; client-side discipline assumed. Schema check is a v1.1 candidate.
  • ZK cardinality attestation is a separate shim (hive-mcp-zk-attestation); not bundled.
