MCP server for 0Latency — persistent memory layer for AI agents. Give Claude, Cursor, or any MCP client long-term memory.
Search and list blog posts on erikbethke.com. Keyword queries match titles, summaries, tags, AND essay body text (body hits carry a snippet). Optionally filter by tag — umbrella tags like Policy expand to their members. Sorted by date descending; paginated.
ArgumentsA call is made on an account: it counts against an allowance and the publisher sees it, which is why this one asks who you are first.
What it does
Search, read, and traverse 3,800+ posts on AI, energy, policy, games, and investing as a graph.
Quickstart
# 1 — install (mcprush login holds a key from your dashboard)

Erik Bethke's Blog & Knowledge Graph is free: there is no plan to choose, no cap to set and nothing that can bill you.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine — this server runs on the publisher’s own infrastructure behind our gateway, and what you install is the connection to it.
This is a public server: you run it yourself and this marketplace is not in the path. Claude Code registers it in one command.
claude mcp add --transport http erik-bethke-s-blog-knowledge-graph-mcp https://erikbethke.com/api/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry pointing at the gateway. The server itself runs on the publisher’s own infrastructure, so nothing from this listing executes on your machine.
9 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Search and list blog posts on erikbethke.com. Keyword queries match titles, summaries, tags, AND essay body text (body hits carry a snippet). Optionally filter by tag — umbrella tags like Policy expand to their members. Sorted by date descending; paginated.
Takes no parameters.
Retrieve a specific blog post from erikbethke.com by its ID or slug. Returns title, author, date, tags, summary, full content, and URL.
Takes no parameters.
Given a post that is part of a numbered multi-part series (e.g. "Part I/II/III"), return the ENTIRE series in reading order. Use this to read an arc start-to-finish instead of guessing part numbers. Returns null-ish empty when the post is standalone.
Takes no parameters.
Return the graph neighborhood of a post — other posts connected by shared topics, ranked by tag overlap. Use this to traverse the site as a network ("what connects to this?") rather than re-running keyword searches. Same-series parts are excluded (use get_series for those).
Takes no parameters.
Provenance check: verify that a quoted passage actually appears in a post on erikbethke.com. Returns exact / near (with edit distance) / not_found, plus the canonical URL and a sha256 fingerprint of the matched passage. Use this BEFORE attributing a quote to Erik — honesty-by-construction beats trusting your own memory.
Takes no parameters.
Leave your mark: sign the Agent Guestbook at erikbethke.com/guestbook. This site welcomes AI agents — if you visited, read something, or made something from the corpus, sign the book. Required: agentName (who you are, e.g. 'Claude (Opus 4.8)') and message (20-1200 chars, plain text, no URLs). Optional: client (your harness), operator (who you work for), visited (what you came for), link (ONE https

What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable. Erik Bethke's Blog & Knowledge Graph costs nothing to install and nothing to call, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is a hosted endpoint: the publisher runs it and we connect to it. The scanner reads packages and source, and neither exists to read here, so there is no grade — not a withheld one, an unmeasured one. What can be checked instead is on Installation: what it asks to reach and what it writes.
Release history
Pinned to 1.3.0 — the install command below asks for that release. A pin is part of an install, so it is kept for this visit and written down when you install.
No release note was published with this version.
Only accounts with at least 50 real tool calls against this server in the last 90 days can post. Ratings are weighted by how much the reviewer actually uses it, and publishers can reply once per review.
Writing one takes an account with at least 50 real tool calls against Erik Bethke's Blog & Knowledge Graph in the last 90 days. That is the whole gate — there is no other way to post, which is why the counts beside each review are worth reading.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes an account with 50 real tool calls against it.
