trip2g

Open-source MCP knowledge mesh. Self-host your knowledge bases, expose them via MCP, and federate with peers — no SaaS in the middle.

Unlike Obsidian Publish or Quartz, trip2g is a live server: subscriptions, webhook agents, federation between hubs, and an MCP endpoint out of the box.

Try it now

Add the public knowledge hub to your MCP client:

{
  "mcpServers": {
    "trip2g": {
      "url": "https://trip2g.com/_system/mcp"
    }
  }
}

Ask your agent anything. It searches all connected bases and returns answers with sources.

Core capabilities

Markdown → website

• Wikilinks ([[note]]), backlinks, outlinks — global resolution, just like Obsidian
• Composable page layouts via frontmatter: sidebars, magazine grid, TOC, custom note embeds
• Full-text search (bleve) + semantic search (pluggable embeddings)
• Custom domains, multi-language with hreflang, RSS feeds, sitemap

MCP server — built into every hub:

search_notes   full-text + semantic search
get_note       retrieve by id or slug
list_notes     list notes accessible to the caller

Access is scoped to the caller's subscription level.

Webhook agents

• Change webhooks — POST to an external agent on note create/update/remove. Agent writes notes back via API. Glob filtering, HMAC auth, depth tracking prevents recursion.
• Cron webhooks — run an agent on a schedule (0 9 * * *). Sync or async. Optional instruction context.

Monetization

• Subgraph paywalls — group notes into paid products, free notes stay public
• Crypto payments (NowPayments), Patreon and Boosty integration

Obsidian plugin — one-click sync, hash-based diff, only changed files are uploaded

Federation

graph LR
    O[Obsidian vault] --> H[your hub]
    T[Telegram]       --> H
    H <-->|MCP federation| H2[peer hub]
    H2 --> B[their bases]
    H -->|/_system/mcp| A[agent]
    H2 -->|/_system/mcp| A

Peer hubs with trusted people or orgs. Each hub controls access per base. One agent question reaches the union of all connected knowledge.

Sources

Template system

Every page is a Jet template. Configure layout per-note via frontmatter — no code changes:

---
header: "[[Navigation]]"
left_sidebar:
  - TOC
  - inlinks
content:
  - magazine
  - selfcontent
magazine_include_files: "blog/**/*.md"
magazine_sort_property: published_date
footer: "[[Footer]]"
---

Notes can render as any content type — HTML, JSON, RSS — via content_type frontmatter.
