Obsidian Vault

The Obsidian Vault MCP server connects your local or synced Obsidian vault to any AI agent through a single hosted MCP endpoint, turning your personal knowledge graph into a queryable, writable resource for Claude, GPT, Gemini, or any other model-agnostic assistant. Instead of manually copy-pasting notes into a chat window, agents can search full-text across your vault, follow backlinks, read frontmatter, and traverse the same graph structure you see in Obsidian's own graph view — all without you exposing raw files or standing up a custom integration for every AI tool you use.

This integration is built for knowledge workers, researchers, consultants, and technical teams who treat Obsidian as their second brain and want that brain accessible to automated workflows. Typical usage includes asking an agent to summarize everything tagged #project-x, auto-link a new meeting note to related existing notes, or have an agent draft a weekly digest pulled straight from your daily notes folder. Because tag management and link creation are handled through the same MCP calls, agents can keep your vault's structure consistent — adding proper wikilinks and tags rather than dumping unstructured text that breaks your existing organization system.

Within BusinessMCP's unified model, the Obsidian Vault connector is provisioned once and exposed at your company's own /api/mcp endpoint, authenticated with a Bearer mcph_* key. That means your notes vault sits alongside your CRM, ad platforms, databases, and support tools in one hosted MCP server rather than as an isolated plugin only one AI client can see. Any team member's agent — whether it's running in Claude Desktop, a custom GPT, or an internal automation — hits the same endpoint and gets the same governed access to the vault, with usage visible in the shared business-intelligence dashboard. That visibility matters for teams using Obsidian as a shared documentation or research layer: you can see which notes get queried most, spot stale areas of the knowledge graph, and understand how AI-assisted note creation is actually being used across the organization.

Because the connector is cookieless and GDPR-friendly by design, it fits naturally into regulated or privacy-conscious environments where personal notes, client research, or internal wikis can't be piped through untracked browser extensions or third-party SaaS scrapers. Search, link creation, tag management, and graph navigation are exposed as discrete, auditable tool calls rather than opaque file access, so security teams can reason about exactly what an agent touched and when.

Pair the Obsidian Vault connector with related productivity and knowledge-base integrations — Notion, Filesystem, or Memory servers — to build a fuller picture of an organization's documentation, and route everything through the same hosted MCP + BI layer so notes, tasks, and files stay in sync no matter which AI agent is doing the querying. Whether you're maintaining a personal Obsidian vault for research or running a team-wide knowledge base, this integration lets you keep Obsidian as the source of truth while letting AI agents read, write, and reason over it responsibly.
