MemberJunction's Model Context Protocol (MCP) server implementation. Exposes MemberJunction entities, AI agents, actions, and prompts as MCP tools that can be consumed by any MCP-compatible AI client (Claude Desktop, Cursor, custom integrations). Supports both SSE and StreamableHTTP transports, API key and OAuth 2.1 authentication, configurable tool filtering, and dynamic tool generation from entity metadata.

# Start with all configured tools

# Start with tool filtering

Dynamically generated from MemberJunction entity metadata. For each configured entity, the server creates:
| Tool Pattern | Description |
|---|---|
Get_<Entity>_Record |
Retrieve a single record by primary key |
Get_<Entity>_Records |
Query records with filtering, sorting, field selection |
Create_<Entity>_Record |
Create a new entity record |
Update_<Entity>_Record |
Update an existing record |
Delete_<Entity>_Record |
Delete a record by primary key |
RunView_<Entity> |
Execute a view with ExtraFilter, OrderBy, Fields, MaxRows |
| Tool | Description |
|---|---|
Run_Agent |
Execute any configured MemberJunction AI agent with conversation history and template data |
| Tool Pattern | Description |
|---|---|
Run_<Action>_Action |
Execute a configured MemberJunction action with parameters |
| Tool Pattern | Description |
|---|---|
Run_<Prompt>_Prompt |
Execute a configured AI prompt with template data |
| Tool | Description |
|---|---|
Get_All_Entity_Metadata |
Retrieve all entity metadata including fields, relationships, and field types |
Configuration is loaded from mj.config.cjs or environment variables. Key settings:
module.exports = {
mcpServerSettings: {
port: 3100,
entities: [
{ entityName: 'Users', operations: ['get', 'list', 'create', 'update', 'delete', 'runview'] },
{ entityName: 'Companies', operations: ['get', 'list', 'runview'] }
],
agents: [
{ agentId: 'agent-uuid', name: 'Sales Assistant' }
],
actions: [
{ actionId: 'action-uuid', name: 'Send Email' }
],
prompts: [
{ promptId: 'prompt-uuid', name: 'Summarize Content' }
]
}
};
The server authenticates requests using MemberJunction API keys. The API key is passed via the x-api-key header and maps to a MemberJunction user context.
When configured, the server acts as both an OAuth resource server and an OAuth proxy:
/.well-known/oauth-protected-resourceThe OAuth proxy handles the authorization flow for MCP clients that don't natively support OAuth, proxying between the client and your identity provider.
Filter which tools are exposed using glob-style patterns:
{
"include": ["Get_*", "Run_Agent", "RunView_Users"],
"exclude": ["*_AuditLogs_*", "Delete_*"]
}
Patterns support:
* -- Match any charactersprefix* -- Match tools starting with prefix*suffix -- Match tools ending with suffix*contains* -- Match tools containing text| Option | Alias | Description |
|---|---|---|
--include |
-i |
Comma-separated include patterns |
