Gnomon
Stop agents from hallucinating calendars and arithmetic by routing date and math work through deterministic Gnomon MCP batch tools.
Overview
Gnomon MCP is a Build-phase MCP server that provides deterministic batch date and math tools for LLM agents.
What is this MCP server?
- Deterministic date and math operations exposed as MCP tools (PyPI gnomon-mcp 0.1.2)
- Batch-oriented design so agents run consolidated computations in one call
- stdio transport via PyPI package identifier gnomon-mcp
- Reduces guesswork on timezone edges, durations, and numeric transforms
- GitHub: lihtness/gnomon-mcp
- Server version 0.1.2
- PyPI package identifier gnomon-mcp with stdio transport
- Repository: github.com/lihtness/gnomon-mcp
What problem does it solve?
Agents confidently output wrong dates, timezones, and sums unless calculations run outside the model.
Who is it for?
Builders adding a tiny deterministic calculation layer to agent automations and codegen pipelines.
Skip if: Heavy scientific computing, symbolic algebra CAS needs, or teams that forbid extra Python MCP dependencies.
What do I get? / Deliverables
Your agent calls Gnomon MCP for batched date and math results you can log, test, and reuse across workflows.
- Registered Gnomon stdio MCP server in agent config
- Tool-call path for verifiable date and math batches
- Reduced correction loops on scheduling and numeric codegen
Recommended MCP Servers
Journey fit
Reliable agent tooling belongs in Build when you harden automations that schedule, calculate, or batch-transform data. Agent-tooling is the shelf for MCP servers that improve tool-call accuracy rather than shipping end-user UI.
How it compares
Specialized datetime and math MCP server, not a general code-execution sandbox or spreadsheet integration.
Common Questions / FAQ
Who is Gnomon MCP for?
Solo developers using MCP agents who keep seeing date and arithmetic mistakes in generated scripts and schedules.
When should I use Gnomon MCP?
During Build agent-tooling when workflows need reliable batch date parsing, deltas, or numeric operations inside tool calls.
How do I add Gnomon MCP to my agent?
Install Gnomon-mcp from PyPI (0.1.2), configure stdio MCP with package identifier Gnomon-mcp, ensure Python runtime is available, and restart your agent host.
