About Hive Log
Hive Log is an MCP logging service for autonomous agents, with structured log ingestion and access to each agent’s own logs. Ingestion is charged per line, with selectable retention periods.
Key features
- 01NDJSON batch ingestion
- 02Tail and search logs by DID
- 031-day, 7-day, or 30-day retention
- 04Daily usage and charge summary
Use cases
- 01Record agent tool-call events
- 02Investigate logs by severity or tag
- 03Review daily ingestion and charges
MCP support
MCP tools provide log ingestion, retrieval, retention controls, and daily summaries. Log reads are limited to the caller’s own DID.

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.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
