This workflow deploys an MCP Neon server and toolkit to a test Meshagent Room in the cloud, suitable for evaluation, prototyping, or short-lived automation sessions. When the Room closes, all services—MCP server, chatbot, and tools—are also terminated.
  1. Install Meshagent with all features: 
    pip install "meshagent[all]"
  2. Sign up and authenticate:
    Follow steps at Meshagent CLI Getting Started
  3. Start a Room-level MCP server agent: 
    meshagent service test --room=test --role=agent --image=meshagent/mcp-neon:latest --env MESHAGENT_PORT=8001  --port="num=8001 path=/webhook liveness=/ type=meshagent.callable" --name=mcp-neon-service-test
    • This creates a temporary room (--room=test) and launches the Neon MCP server in the room as a cloud agent. The service and room will be auto-removed if inactive.
  4. Launch a chatbot in the room with the Neon toolkit: 
    meshagent chatbot join --room=test --agent-name=mcp-neon --name=mcp-neon --toolkit=mcp-neon
    • Multiple toolkits can be used per room with the same agent.
    • The command output will provide a URL to access the room.
  5. Test the integration:
    Open the provided room URL in your browser, and chat with the agent. Any requests will be handled using the Neon MCP server’s tools.

Project Level Deployment: Persistent Services for All Rooms

For production use, you can create persistent agents in your Meshagent project that automatically join every new project room. This ensures the MCP server and tool-enabled chatbot are always available—no manual setup or process hosting needed.
  1. Create a persistent MCP server agent: 
    meshagent service create --role=agent --image=meshagent/mcp-neon:latest --env MESHAGENT_PORT=8001  --port="num=8001 path=/webhook liveness=/ type=meshagent.callable" --name=mcp-neon-service
  2. Create a persistent chatbot with the Neon toolkit: 
    meshagent service create \
  --image="meshagent/cli:latest" \
  --port="num=9001 path=/agent liveness=/ type=meshagent.callable participant_name=mcp-neon-chatbot" \
  --env="MESHAGENT_PORT=9001" \
  --name="mcp-neon-chatbot-service" \
  --command="meshagent chatbot service --agent-name=mcp-neon-chatbot --toolkit=mcp-neon"
Once these services are set up, every new Meshagent room in your project will automatically get a live MCP server agent and Neon-toolkit-enabled chatbot, eliminating the need to run or manage these processes separately.

​
Tool Details

__node_version
Get the Node.js version used by the MCP server. complete_database_migration
Complete a migration that was prepared and verified in a temporary branch, applying final changes to the main branch. complete_query_tuning
Finalize (commit or discard) performance improvements identified during query tuning, ensuring cleanup of temporary test branches and proper application of changes. create_branch
Create a new branch in a Neon project for isolated development or testing. create_project
Provision a new, fully managed Neon project. delete_branch
Remove a branch from a Neon project. delete_project
Delete an existing Neon project and its resources. describe_branch
Get a complete tree view of all objects (databases, schemas, tables, views, functions) in a specific branch. describe_project
Summarize a Neon project’s structure, resources, and configuration. describe_table_schema
Return the schema for a given table to support tooling and development. explain_sql_statement
Analyze a SQL statement’s execution plan as run in PostgreSQL (EXPLAIN). get_connection_string
Generate a PostgreSQL connection string with useful defaults. get_database_tables
List the tables present in a Neon-managed database. list_projects
Show all the Neon projects a user has access to. prepare_database_migration
Generate migration SQL from natural language requests, apply changes to a safe, temporary branch, and present results for user confirmation before merging to production. prepare_query_tuning
Automatically analyze slow SQL queries, suggest and test optimizations in a temporary branch, then allow review of performance before applying fixes to the main branch. provision_neon_auth
Provision authentication for a Neon project using modern Stack Auth integration. run_sql
Run a single SQL command against your Neon database, using temporary branches when needed for safety. run_sql_transaction
Run a multi-statement SQL transaction, again with support for temporary branches for testing.
