Logi Sheets MCP Server

A real spreadsheet engine your agent can think in. Excel-compatible formulas it doesn't have to do in its head, a table it addresses by name instead of by coordinate, and a genuine .xlsx at the end that a person can open, audit and keep using. Its 29 documented tools cover block, chart, pivot, workbook. It runs locally over stdio via the published package.

People who work with block, chart and pivot and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Logi Sheets

Claude Code

claude mcp add logisky-logisheets-mcp -- npx -y logisheets-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "logisky-logisheets-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "logisheets-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-08-19 - young repo, little track record yet

license MIT - declared in the repository

npm package logisheets-mcp - unscoped; check the name against the project README before installing

registry namespace io.github.logisky is GitHub-verified and matches the repo owner

03 · What Logi Sheets can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can start a fresh workbook, or load an existing .xlsx. Optional - one appears on first use, write a real .xlsx. This is how work gets handed back, evaluate a formula and return the value. Nothing is stored, and create a named table. First field is the row key.

Capability map

Tools grouped from the project's README - what Logi Sheets lets an agent do.

Block

11 tools - e.g. A block's schema, keys, field rules, description, and optionally its values.; Create a named table. First field is the row key.; Adopt a table that is already in ordinary cells, in place.

describe_block · create_block · convert_to_block · set_block_description · add_block_rows · delete_block_rows…

Chart

4 tools - e.g. Chart arbitrary A1 ranges - the raw-cell counterpart.; The charts on a sheet: type, title, and the ranges each series reads.; Reconfigure a chart in place - type, series, axes, labels.

chart_insert · chart_list · chart_update · chart_delete

Pivot

3 tools - e.g. Cross-tabulate a block: one row per group, one column per value, live.; Reshape a pivot in place - and the only way to repair a broken one.; Bring a pivot's rows and columns back in line with its source.

create_pivot · edit_pivot · refresh_pivot

read & search

2 tools - e.g. Every sheet and block, plus where the next block should go.; Which cells break their field's validation rule, and why.

list_blocks · list_violations

Open

1 tool - e.g. Start a fresh workbook, or load an existing .xlsx. Optional - one appears on first use.

open_workbook

Save

1 tool - e.g. Write a real .xlsx. This is how work gets handed back.

save_workbook

Export

1 tool - e.g. The file as base64, for hosts with no shared filesystem.

export_xlsx

Eval

1 tool - e.g. Evaluate a formula and return the value. Nothing is stored.

eval_formula
