notes.read with include: ['stats'] fails with output schema validation error

[OliverBokan]

Description

Calling notes.read with include: ['stats'] returns an MCP output validation error. The headings and links fields in the stats response appear to be objects instead of the numbers the schema expects.

Error

MCP error -32602: Output validation error: Invalid structured content for tool notes.read: [
  {
    "expected": "number",
    "code": "invalid_type",
    "path": ["stats", "headings"],
    "message": "Invalid input: expected number, received object"
  },
  {
    "expected": "number",
    "code": "invalid_type",
    "path": ["stats", "links"],
    "message": "Invalid input: expected number, received object"
  }
]

Steps to reproduce

{
  "path": "any-note.md",
  "include": ["stats"]
}

Expected behavior

notes.read with include: ['stats'] should return numeric counts for headings and links.

Workaround

Use include: ['content'] or include: ['metadata'] instead — these work correctly.

Environment

• kObsidian: latest (via npx -y kobsidian-mcp)
• Client: Claude Cowork (Windows)
• OS: Windows 11

Thanks for the detailed report and validation error output. This is fixed in #28, which now returns schema-compatible numeric stats for notes.read when called with include: ["stats"].

Thanks again for reporting that error. I think the cause was
otes.read returning nested stats fields where the MCP output schema expected numeric counts. It is now fixed and released in v0.3.3: https://github.com/bezata/kObsidian/releases/tag/v0.3.3
