AFFiNE MCP Server Integration

Skill by ara.so — MCP Skills collection.

Overview

AFFiNE MCP Server is a Model Context Protocol server that exposes AFFiNE workspaces, documents, databases, and collaboration features to AI assistants. It supports both AFFiNE Cloud and self-hosted deployments, offering 85+ tools across workspace management, document operations, database manipulation, and organizational features.

Key capabilities:

• Connect AI assistants (Claude Code, Cursor, Codex CLI, Claude Desktop) to AFFiNE
• Read, create, update, and delete documents programmatically
• Manage databases, collections, and organizational structures
• Access via stdio (local) or HTTP (remote) transports
• Semantic page composition and template instantiation
• Block-level document mutation and structured data handling

Common Workflow Patterns

Creating a Project Structure

// 1. Create workspace
const workspace = await create_workspace({
  name: "Q1 Project",
  description: "Project tracking workspace"
});

// 2. Create main document
const mainDoc = await create_doc({
  workspaceId: workspace.id,
  title: "Project Overview",
  text: "# Project Overview\n\nKey objectives..."
});

// 3. Create database for task tracking
const database = await create_database({
  workspaceId: workspace.id,
  docId: mainDoc.id,
  name: "Task Tracker"
});

// 4. Add columns
await add_database_column({
  workspaceId: workspace.id,
  docId: mainDoc.id,
  databaseId: database.id,
  name: "Priority",
  type: "select",
  options: ["High", "Medium", "Low"]
});

// 5. Add initial tasks
await add_database_row({
  workspaceId: workspace.id,
  : mainDoc.,
  : database.,
  : {
    : ,
    : 
  }
});

Document Search and Update

// 1. Search for documents
const results = await search_docs({
  workspaceId: "workspace-id",
  query: "meeting notes",
  limit: 5
});

// 2. Find specific document by exact title
const doc = await get_doc_by_title({
  workspaceId: "workspace-id",
  title: "Weekly Standup - 2024-01-15"
});

// 3. Read current content
const content = await read_doc({
  workspaceId: "workspace-id",
  docId: doc.id
});

// 4. Append new content
const updatedText = content.text + "\n\n## Action Items\n- Follow up on design";

await update_doc({
  workspaceId: "workspace-id",
  docId: doc.id,
  text: updatedText
});

Using Templates

// 1. List available templates
const templates = await list_templates({
  workspaceId: "workspace-id"
});

// 2. Inspect template to understand structure
const template = await inspect_template({
  workspaceId: "workspace-id",
  templateId: templates[0].id
});

// 3. Create document from template with placement
const newDoc = await create_doc_from_template({
  workspaceId: "workspace-id",
  templateId: templates[0].id,
  title: "Q1 Planning Doc",
  folderId: "planning-folder-id"
});

Semantic Page Composition

// Compose a structured document with intent
const pageIntent = {
  pageTitle: "Product Launch Plan",
  sections: [
    {
      heading: "Executive Summary",
      content: "Overview of product launch strategy..."
    },
    {
      heading: "Timeline",
      content: "Key milestones and dates",
      database: {
        name: "Launch Milestones",
        columns: [
          { name: "Milestone", type: "text" },
          { name: "Date", type: "date" },
          { name: "Owner", type: "text" }
        ]
      }
    }
  ]
};

// Use semantic composition tool
const result = await compose_semantic_page({
  workspaceId: "workspace-id",
  intent: JSON.stringify(pageIntent)
});

Database Intent Composition

// Create complex database structure from high-level intent
const dbIntent = {
  name: "Bug Tracker",
  columns: [
    { name: "Title", type: "text" },
    { name: "Severity", type: "select", options: ["Critical", "High", "Medium", "Low"] },
    { name: "Status", type: "select", options: ["Open", "In Progress", "Fixed", "Closed"] },
    { name: "Assigned To", type: "text" },
    { name: "Due Date", type: "date" }
  ],
  initialRows: [
    {
      "Title": "Login page crash",
      "Severity": "Critical",
      "Status": "Open"
    }
  ]
};

const result = await compose_database_from_intent({
  workspaceId: "workspace-id",
  docId: "doc-id",
  intent: JSON.stringify(dbIntent)
});

Security Configuration

Tool Profile Restriction

# Limit to read-only operations
export AFFINE_TOOL_PROFILE=read_only

# Core tools only (no experimental features)
export AFFINE_TOOL_PROFILE=core

# Authoring tools (read + write, no admin)
export AFFINE_TOOL_PROFILE=authoring

# Full access (default)
export AFFINE_TOOL_PROFILE=full

Fine-Grained Tool Control

# Disable entire tool groups
export AFFINE_DISABLED_GROUPS=destructive,admin,docs.database

# Disable specific tools
export AFFINE_DISABLED_TOOLS=delete_workspace,delete_doc,trash_doc

HTTP Server Security

# Enable bearer token authentication
export AFFINE_MCP_AUTH_MODE=bearer
export AFFINE_MCP_HTTP_TOKEN=${MCP_HTTP_TOKEN}

# Use HTTPS in production
export MCP_HTTP_PORT=3000
# Then reverse proxy with nginx/caddy for TLS

affine-mcp config-path
ls -la $(affine-mcp config-path)

Common Errors

"Authentication failed"

• Verify API token is correct and not expired
• For AFFiNE Cloud, use API token (not email/password)
• Check token has appropriate scopes

"Workspace not found"

• Ensure workspace exists and is server-backed (not browser-local)
• Verify user has access to workspace
• Check workspace ID is correct

"Tool not found"

• Check AFFINE_TOOL_PROFILE and AFFINE_DISABLED_GROUPS settings
• Verify tool name matches manifest exactly
• Update to latest version: npm i -g affine-mcp-server@latest

"Connection refused" (HTTP mode)

• Verify server is running: docker ps or check process
• Check firewall rules allow port access
• Verify MCP_HTTP_PORT matches client configuration

Debug Mode

# Enable debug logging
LOG_LEVEL=debug affine-mcp

# Or with environment variable
export LOG_LEVEL=debug
affine-mcp

Verify Tool Availability

# List all available tools
affine-mcp status --json | jq '.tools'

# Check specific tool
affine-mcp status --json | jq '.tools[] | select(.name == "create_doc")'

Advanced Patterns

Capability and Fidelity Reporting

// Check document capabilities before operations
const capabilities = await report_doc_capabilities({
  workspaceId: "workspace-id",
  docId: "doc-id"
});

// Returns: { canEdit, canComment, canShare, exportFormats, ... }

// Check content fidelity (what blocks/features are supported)
const fidelity = await report_content_fidelity({
  workspaceId: "workspace-id",
  docId: "doc-id"
});

Block-Level Mutations

// Append block to document
await append_block({
  workspaceId: "workspace-id",
  docId: "doc-id",
  blockType: "paragraph",
  content: "New paragraph text"
});

// Insert block at specific position
await insert_block({
  workspaceId: "workspace-id",
  docId: "doc-id",
  afterBlockId: "block-id",
  blockType: "heading",
  content: "New Section",
  level: 2
});

Workspace Blueprints

// Create workspace from blueprint
const blueprint = {
  name: "Team Sprint",
  folders: ["Planning", "Design", "Development"],
  templates: ["standup", "retrospective"],
  databases: ["task-tracker"]
};

const workspace = await create_workspace_from_blueprint({
  blueprint: JSON.stringify(blueprint)
});

Collection Rules and Sync

// Create collection with rules
await create_collection({
  workspaceId: "workspace-id",
  name: "Meeting Notes",
  rules: {
    tagFilter: ["meeting"],
    autoSync: true
  }
});

// Sync collection (apply rules)
await sync_collection_rules({
  workspaceId: "workspace-id",
  collectionId: "collection-id"
});

Best Practices

1. Use API tokens - More secure and reliable than email/password
2. Enable health checks - Use /healthz and /readyz for containerized deployments
3. Restrict tool profiles - Use AFFINE_TOOL_PROFILE=authoring in production to prevent accidental deletions
4. Rotate tokens regularly - Generate new API tokens periodically
5. Use HTTPS - Always use TLS for remote deployments
6. Handle errors gracefully - Check tool responses for error fields
7. Batch operations - Use semantic composition and database intent tools for complex structures
8. Verify before destructive ops - Use read tools to confirm before delete/trash operations
