At a Glance & Executive Verdict
Fermat MCP
Data Science Tools · Local stdio
Quality: 57/100 (Good) | Auth: No auth required
Stella MCP
Data Science Tools · Local stdio
Quality: 57/100 (Good) | Auth: No auth required
Verdict Summary: Choose Fermat MCP if you need specialized Data Science Tools tools running via a local process. Choose Stella MCP if your workspace requires Data Science Tools integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Fermat MCP when:
You need dedicated capabilities in the Data Science Tools domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Primary tools included: NumPy numerical operations, SymPy symbolic algebra and calculus, Linear algebra and matrix functions.
The ultimate math engine unifying SymPy, NumPy & Matplotlib in one powerful server. Perfect for developers & researchers needing symbolic algebra, numerical computing, and data visualization.
Create, read, validate, and save Stella system dynamics models (.stmx files in XMILE format) for scientific simulation and modeling.
Fermat MCP is categorized under Data Science Tools and uses a local stdio subprocess. In contrast, Stella MCP belongs to Data Science Tools using local stdio subprocess. Select Fermat MCP when you need capabilities focused on data science tools and Stella MCP when you require tools for data science tools.
Create and populate a model in one call: sim specs, stocks, auxiliaries, flows, connectors, and modules. All-or-nothing — on any item error nothing is registered and the error names the failing item (stage + index). Connector sync and validation run by default, so the response doubles as an inspection.
add_variables
Add multiple stocks, auxiliaries, flows, connectors, and/or modules to an existing model in one call. All-or-nothing — on any item error the model is left unchanged and the error names the failing item (stage + index).
set_sim_specs
Update simulation time settings on an existing model
add_stock
Add a stock (reservoir) to the current model
update_stock
Update stock fields while preserving relationships
add_flow
Add a flow between stocks in the current model
update_flow
Update flow fields while preserving structural stock links
add_aux
Add an auxiliary variable (parameter or intermediate calculation) to the current model
update_aux
Update auxiliary variable fields
add_connector
Add a connector (dependency arrow) between variables
sync_connectors_from_equations
Add missing dependency connectors inferred from flow and auxiliary equations
