What is the Capacities MCP Server?
Connect your Capacities account to any AI agent and take full control of your object-based personal knowledge management through natural conversation.
What you can do
- Spaces & Structures — Enumerate your personal spaces and discover the exact object type structures mapping your active environment.
- Object Instantiation — Build new typed graph objects complying precisely with the predefined structure parameters.
- Daily Note Appends — Send quick thoughts, summaries, and Markdown text directly into your mapped daily note log.
- Content Lookups — Execute rapid keyword searches targeting explicit object hierarchies to track down active nodes.
- Rich Link Saving — Parse and inject web URLs dynamically into your space as Weblink objects, triggering automatic previews.
- Media & Tagging — Attach images and add tags to existing objects to organize your graph relations instantly.
How it works
- Subscribe to this server
- Navigate to your Capacities app Settings to grab your Personal Token
- Start fetching and creating deep knowledge blocks dynamically from Claude or Cursor
Who is this for?
- Researchers & Writers — Instantly instruct your agent to capture weblinks or draft quick notes straight into today’s daily log without switching context.
- Developers — Allow AI coding assistants to document system architectures automatically by injecting structured Markdown objects.
- Knowledge Workers — Command the agent to search your Capacities workspace and extract specific object properties to brief you before a meeting.
Built-in capabilities (10)
Add a structural categorical Tag linking explicitly dynamically grouping related Graph items via relations
Create a new typed object in a Capacities space bounded by specific graph rules instantiating entities
Retrieve a specific full explicit object by ID accessing its root graph data traversing properties internally
Retrieve detailed information about a Capacities space including all object types (structures), their property definitions, and configuration
Get all object type definitions (structures) within a Capacities space exposing exact metadata parameters limitlessly
List all personal spaces in the Capacities account. Spaces are top-level containers for organizing objects, notes, and knowledge
Search for content across a specific Capacities space by title or explicit keywords tracking exact nodes
Locate and attach an explicit Media payload explicitly binding it directly onto existing specific record scopes
Append strict Markdown textual payloads to the dynamically mapped daily note explicitly linking content blocks

Why CrewAI?
When paired with CrewAI, Capacities becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Capacities tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.
- —
Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools
- —
CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the
mcpsparameter and agents auto-discover every available tool at runtime - —
Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls
- —
Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

Frequently asked questions
Can my AI agent automatically funnel research links into my Capacities daily note?
Yes. It can append raw Markdown to your Daily Note dynamically, or use the dedicated WebLink endpoint to natively scrape and save beautifully previewed URLs into your specified space. This gives you a fast workflow for daily link-hoarding right from your chat tools.
Will the agent know the specific object structures configured in my custom Capacities space?
Absolutely. Before creating nodes, your agent pulls constraints using the get_structures capability. It reads the schemas, understands which properties are locked or required (e.g., Dates vs Checkboxes), and constructs the new object JSON mapping perfectly inside the space.
Is the agent capable of categorizing objects with new tags automatically?
Yes. Once an object is created or fetched via lookup, the AI can employ the tag modification tool to link categorical boundaries accurately. It's a frictionless way to organize hundreds of loosely coupled notes into connected knowledge topics without any manual toggles.
How does CrewAI discover and connect to MCP tools?
CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.
Can different agents in the same crew use different MCP servers?
Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.
What happens when an MCP tool call fails during a crew run?
CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.
Can CrewAI agents call multiple MCP tools in parallel?
CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.
Can I run CrewAI crews on a schedule (cron)?
Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
MCP tools not discovered
Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
Agent not using tools
Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
Timeout errors
CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
Rate limiting or 429 errors
Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
