Tamper-evident audit log service for agent-to-agent transactions
Install
Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).
claude mcp add --transport http hive-log 'https://hive-mcp-log.onrender.com/mcp'

hive-mcp-log
Inbound structured-log ingestion shim — 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 — inbound only, no outbound calls.
Council provenance: Tier A inbound metering shim. Companion to
hive-mcp-auctionandhive-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.

MCP tools
| Tool | Tier | Description |
|---|---|---|
log_ingest | metered | Ingest NDJSON batch (max 4 MB / 10k lines). $0.0001/line + retention surcharge. |
log_tail | 0 (free) | Return last N log lines for the calling DID. |
log_search | 0 (free) | Search own-DID logs by time/severity/tag/free-text. |
log_retention_get | 0 (free) | Return current tier + bytes stored. |
log_retention_set | 0 (free) | Change retention tier (1d/7d/30d). |
log_today | 0 (free) | Today aggregate — ingests, lines, bytes, charge_usd. |
REST endpoints
| Method | Path | Purpose |
|---|---|---|
POST | /v1/log/ingest | Ingest NDJSON batch. Returns 402 envelope first, accepts tx_hash to settle. |
GET | /v1/log/tail | Last N lines for did. |
GET | /v1/log/search | Search by time/severity/tag/q. Cursor pagination. |
GET | /v1/log/retention | Current retention tier + monthly cost projection. |
PATCH | /v1/log/retention | Change retention tier for a DID. |
GET | /v1/log/today | Today aggregate (Tier 0, free). |
POST | /mcp | MCP JSON-RPC 2.0 surface. |
GET | /health | Service health. |
Pricing
Ingest: $0.0001 per log line
Retention:
1d (default) free
7d $0.005 / MB
30d $0.02 / MB
Tail / search (own-DID): Tier 0 — free
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.
