HIVEMIND adds persistent memory and bi-temporal time-travel queries to Claude Code through 22 MCP tools across memory, web intelligence, coding intelligence, and historical queries. A developer uses it to let an agent recall prior context and reason over how knowledge changed over time.

Key points

Persistent agent memory
Bi-temporal time travel
22 MCP tools

README.md

claude-hivemind

A Claude Code plugin that gives your AI persistent memory + bi-temporal time travel across sessions, machines, and projects — backed by HIVEMIND.

22 MCP tools across four streams:

Memory (9): save_memory, recall, get_memory, list_memories, update_memory, delete_memory, save_conversation, traverse_graph, query_with_ai
Web Intelligence (4): web_search, web_crawl, web_job_status, web_usage
Coding Intelligence (6): ingest_code, recall_bugs, log_decision, track_refactor, test_coverage, why_code
Time Travel (3): code_at, code_diff, code_timeline

Install

/plugin marketplace add amar3012005/claude-hivemind
/plugin install claude-hivemind
/hivemind:connect

/hivemind:connect opens your browser for OAuth (Zitadel SSO or Google), then writes credentials to ~/.hivemind-claude/credentials.json. The MCP server picks them up on the next session.

Commands

Command	Description
`/hivemind:connect`	Sign in via browser OAuth
`/hivemind:logout`	Remove cached credentials
`/hivemind:index-codebase`	Bulk-ingest the current repo so future sessions inherit context

Hooks

SessionStart runs scripts/ensure-auth.cjs to load credentials into env vars (HIVEMIND_API_KEY, HIVEMIND_USER_ID) for the MCP bridge.

Skill: memory-discipline

The plugin ships a skill (memory-discipline) that documents the recall→ingest→log→track loop. Claude Code activates it on every session so the model knows to use HIVEMIND aggressively.

Architecture

Control plane: https://api.hivemind.davinciai.eu:8040 — auth, OAuth callbacks, API key issuance, multi-tenant proxy.
Core API: https://core.hivemind.davinciai.eu:8050 — memory ingest, recall, graph traversal, MCP bridge.
MCP bridge: npx -y @amar_528/mcp-bridge hosted --url <core>/api/mcp/servers/<user_id> — relays Claude Code MCP calls to your tenant-scoped HIVEMIND endpoint.

Configuration

Override defaults via env vars:

Env	Default	Purpose
`HIVEMIND_CONTROL_PLANE`	`https://api.hivemind.davinciai.eu:8040`	Auth + bootstrap
`HIVEMIND_CORE_API`	`https://core.hivemind.davinciai.eu:8050`	MCP + REST API
`HIVEMIND_AUTH_PORT`	`19876`	Local OAuth callback port
`HIVEMIND_AUTH_TIMEOUT_MS`	`120000`	Browser OAuth timeout

Privacy

Credentials live only in ~/.hivemind-claude/credentials.json (mode 600, your home dir). Never committed, never sent off-machine. The plugin contains no telemetry. Server-side data lives in EU (Frankfurt), GDPR-compliant.
