Fix MCP server documentation to reference correct entry point

[andreibogdan]

Description

This PR fixes incorrect references to the MCP server entry point in the documentation. Users following the current documentation encounter "No such file or directory" errors because the documented filename graphiti_mcp_server.py doesn't exist at the project root.

Problem

When users try to run commands from the README such as:

uv run graphiti_mcp_server.py --database-provider neo4j

They receive:

error: Failed to spawn: `graphiti_mcp_server.py`
  Caused by: No such file or directory (os error 2)

Solution

Updated all documentation references from graphiti_mcp_server.py to main.py, which is the actual entry point located in the mcp_server/ directory.

Changes

Files Modified

• mcp_server/README.md - Updated 7 command examples across multiple sections:

  • Running with Neo4j (2 occurrences)
  • Running with FalkorDB (2 occurrences)
  • MCP client stdio configuration example (1 occurrence)
  • Cursor IDE integration (1 occurrence)
  • Claude Desktop integration (1 occurrence)

• mcp_server/config/mcp_config_stdio_example.json - Updated example configuration path

Total Changes

• 2 files changed, 8 insertions(+), 8 deletions(-)

Testing

Verified the fix by:

1. ✅ Running uv run main.py --help successfully
2. ✅ Confirming no remaining references to old filename: grep -r "graphiti_mcp_server\.py" mcp_server/README.md returns empty
3. ✅ Running unit tests: 6/6 tests passed
   • Configuration loading tests
   • CLI argument override tests
   • stdio transport tests

Additional Context

The actual file structure is:

• mcp_server/main.py - Entry point wrapper script
• mcp_server/src/graphiti_mcp_server.py - Implementation

The main.py wrapper imports and runs the actual server, maintaining proper package organization while providing a convenient entry point.
