What is the Tana MCP Server?
Translate your AI conversation into structured personal knowledge management seamlessly with the Tana MCP connector. Evolve your LLM into a dedicated ontological architect capable of pushing rich, contextual data fragments straight into your workspace. Bypass tedious manual entry by programming your assistant to dynamically categorize thoughts, mint native ontological classes (Supertags), and instantiate multi-level hierarchies inside your Tana graph while maintaining maximum focus in your local environment.
What you can do
- Node Structuring — Swiftly inject clean data fragments anywhere by defining paths invoking
add_nodeor securely drop ideations asynchronously into your capture zone utilizingadd_to_inbox. - Ontology & Metadata — Formalize data classifications mapping real-world objects using
define_supertagand instantiate them powerfully utilizingadd_tagged_nodeandadd_node_with_fields. - Hierarchy & Linking — Push whole outline structures programmatically executing
add_node_with_childrenand enforce complex bi-directional network paths executingadd_node_reference. - Specialized Datatypes — Effortlessly instantiate formatted daily operations leveraging
add_checkbox_task, temporal entries mappingadd_date_node, or external resources resolving viaadd_url_bookmark.
How it works
- Append the generic Tana matrix module correctly inside your Vinkius connective logic workspace.
- Obtain an active
TANA_API_TOKEN(reserved to Tana Plus/Pro accounts) within Workspace Settings and enforce its security parameter within your local environment. - Prompt graph inputs naturally: "Send a structured meeting note to my inbox with the 'Agenda' supertag, and include three checkbox tasks as its children."
Who is this for?
- Knowledge Workers — Programmatically dispatch asynchronous memos, capturing multi-tiered references avoiding heavy manual logging friction.
- Productivity Systems Engineers — Solidify operational ontologies strictly managing Supertag instantiations verifying schemas systematically.
- Researchers & Analysts — Build deep graph linkages seamlessly tying bookmarks, date blocks, and deep nested lists via streamlined prompt interactions.
Built-in capabilities (10)
Optionally set initial done status. Creates a checkbox/todo item in the Tana inbox
Format: YYYY-MM-DD. Creates a date-typed node in the Tana inbox
Provide a target node ID (or "INBOX", "LIBRARY") and the node name. Creates a new node in a specific Tana location
Provide a label and the target node ID. Creates a reference node linking to an existing node
Provide a name and comma-separated children. Creates a parent node with multiple child nodes
Provide name, supertag ID, and field data as a JSON object. Creates a supertagged node with structured field values
g. #meeting, #person). Requires the supertag ID from Tana schema. Creates a new node with a supertag applied
Quickly adds a new node directly to the Tana Inbox
Creates a URL-typed node in Tana
Provide a name and description. Defines a new supertag in the Tana schema

Every request between LangChain and Tana is protected by our secure gateway. We automatically keep your sensitive data private, prevent unauthorized access, and let you disconnect instantly at any time.
Frequently asked questions
Can it apply Supertags with pre-filled fields?
Yes. Use add_node_with_fields to create a node with a specific Supertag and populate its attributes in a single call.
Are there limits on nested hierarchies?
No practical limits beyond your token window. The add_node_with_children tool accepts arrays of child nodes and populates the hierarchy in a single request.
Which Tana plan is required?
API access is available on Tana Plus and Pro plans. Free accounts do not have API tokens. Generate your token from Workspace Settings in the Tana web app.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
