Local stdio MCP server exposing unified Claude chat history (claude.ai export + Claude Code sessions) as ranked, scoped, structured search.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"claude-archive-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

# claude-archive-mcp > Local stdio MCP server that exposes your unified Claude chat history > (claude.ai export + Claude Code sessions) to Claude Code as ranked, scoped, > structured search. **Status:** v1.14.0 · **Author:** Mike Andersen · **License:** PolyForm Noncommercial 1.0.0 When you reference past work — *"did we settle this in nortam_dev last month?"*, *"find the TAP routing analysis"*, *"what did Claude Code commit on April 14?"* — Claude Code reaches for this server instead of asking you to summarize. ## Two sources, one index | Source | `source` | Origin | |---|---|---| | claude.ai export | `claude_ai` | `~/.claude/Exported_Chats/conversations.json` + `projects/` | | Claude Code sessions | `claude_code` | `~/.claude/projects/**/*.jsonl` | Both feed one `conversations` table; the same tools search across both. ## Tools `search_chats` · `get_chat` · `list_projects` · `list_recent_chats` · `search_within_chat` · `archive_stats` · `timeline` · `find_related_chats` · `get_digest` · `recall` · `get_session_lineage` — eleven read-only, source-aware tools. See [`docs/TOOLS.md`](docs/TOOLS.md). The server also exposes a per-project **resource** (`claude-archive://project/{source}/{identifier}`) — a dynamic markdown project overview. **Digest:** `get_digest` (tool) or `python scripts/digest.py --weekly` (also `/digest`) — a markdown activity recap over a rolling daily/weekly window; both share one aggregator. **Semantic search (optional):** `find_related_chats` ranks conversations by embedding cosine. It needs the optional extra — `pip install -e .[embeddings]`, then `python scripts/embed.py --backfill` (also `/embed`). The server itself stays inference-free. **Comprehension sidecars (v1.4.0):** `search_chats` and `find_related_chats` each carry an additive semantic **sidecar tier** — matches against per-conversation, LLM-authored comprehension sidecars (an abstract plu…
