Quantitative Researcher MCP Server

An MCP server implementation that provides tools for managing quantitative research knowledge graphs, enabling structured representation of research projects, datasets, variables, hypotheses, statistical tests, models, and results. This server helps quantitative researchers organize their data, track their analyses, evaluate hypotheses, and generate insights from numerical data.

Features

- Study Session Management: Track research analysis sessions with unique IDs and record progress over time
- Hypothesis Testing: Track hypotheses, their associated tests, and resulting conclusions
- Dataset Management: Organize and track descriptive statistics and variables within datasets
- Statistical Analysis: Record statistical tests, models, and their results
- Variable Relationships: Track correlations, predictions, and other relationships between variables
- Research Question Tracking: Link data analyses to specific research questions
- Data Visualization: Document visualizations created from datasets and results
- Model Performance: Monitor statistical model performance metrics
- Research Finding Documentation: Link findings to supporting statistical evidence
- Research Methodology Documentation: Track methodological decisions and approaches

Entities

The Quantitative Researcher MCP Server recognizes the following entity types:

- project: Overall research study
- dataset: Collection of data used for analysis
- variable: Specific measurable attribute in a dataset
- hypothesis: Formal testable statement
- statisticalTest: Analysis method applied to data
- result: Outcome of statistical analysis
- analysisScript: Code used to perform analysis
- visualization: Visual representation of data
- model: Statistical/mathematical model
- literature: Academic sources
- researchQuestion: Formal questions guiding the study
- finding: Results or conclusions
- participant: Research subjects
- status: Entity status values (active, completed, pending, abandoned)
- priority: Priority level values (high, low)

Relationships

Entities can be connected through the following relationship types:

- correlates_with: Statistical correlation between variables
- predicts: Predictive relationship from independent to dependent variable
- tests: Statistical test examines hypothesis
- analyzes: Analysis performed on dataset
- produces: Analysis produces result
- visualizes: Visualization displays data or result
- contains: Hierarchical relationship
- part_of: Entity is part of another entity
- depends_on: Dependency relationship
- supports: Evidence supporting a hypothesis or finding
- contradicts: Evidence contradicting a hypothesis or finding
- derived_from: Entity is derived from another entity
- controls_for: Variable/method controls for confounds
- moderates: Variable moderates a relationship
- mediates: Variable mediates a relationship
- implements: Script implements statistical test/model
- compares: Statistical comparison between groups/variables
- includes: Model includes variables
- validates: Validates a model or result
- cites: References literature
- has_status: Links entities to their current status (active, completed, pending, abandoned)
- has_priority: Links entities to their priority level (high, low)
- precedes: Indicates that one process or activity comes before another in a sequence

Available Tools

The Quantitative Researcher MCP Server provides these tools for interacting with research knowledge:

startsession

Starts a new quantitative research session, generating a unique session ID and displaying current research projects, datasets, models, visualizations, and previous sessions. Shows status information via has_status relations, priority levels via has_priority relations, and identifies activities ready to be worked on next based on sequential process relationships.

loadcontext

Loads detailed context for a specific entity (project, dataset, variable, etc.), displaying relevant information based on entity type. Includes status information, priority levels, and sequential process relationships.

endsession

Records the results of a research session through a structured, multi-stage process: 1. summary: Records session summary, duration, and project focus 2. datasetUpdates: Documents updates to datasets during the session 3. newAnalyses: Records new statistical analyses performed 4. newVisualizations: Tracks new data visualizations created 5. hypothesisResults: Documents results of hypothesis testing 6. modelUpdates: Records updates to statistical models 7. statusUpdates: Records changes to entity status values 8. projectStatus: Updates overall project status, priority assignments, and sequential relationships 9. assembly: Final assembly of all session data

buildcontext

Creates new entities, relations, or observations in the knowledge graph: - entities: Add new research entities (projects, datasets, variables, status, priority, etc.) - relations: Create relationships between entities (including has_status, has_priority, precedes) - observations: Add observations to existing entities

deletecontext

Removes entities, relations, or observations from the knowledge graph: - entities: Remove research entities - relations: Remove relationships between entities (including status, priority, and sequential relations) - observations: Remove specific observations from entities

advancedcontext

Retrieves information from the knowledge graph: - graph: Get the entire knowledge graph - search: Search for nodes based on query criteria - nodes: Get specific nodes by name - related: Find related entities - status: Find entities with a specific status value (active, completed, pending, abandoned) - priority: Find entities with a specific priority value (high, low) - sequence: Identify sequential relationships for research processes

Example Prompts

Starting a Session

Let's start a new quantitative research session for my Climate Impact Study project.

Loading Research Context

Load the context for the Climate Impact Study project so I can see the current state of my statistical analyses.

Recording Session Results

I've just finished analyzing data for my Climate Impact Study. I ran three new regression models to test the relationship between temperature and crop yield, created two visualizations of the correlation patterns, and confirmed our hypothesis about rainfall effects. I've marked the temperature analysis as complete and assigned high priority to the regional variation analysis. The model performance improved by 15% after controlling for regional variations.

Managing Research Knowledge

Create a new variable called "Annual Precipitation" that's part of the "Climate Measures" dataset with observations noting it's normally distributed with a mean of 34.5 inches. Set its status to active and make it precede the "Crop Yield Analysis" process.

Update the status of the "Data Cleaning" process to "completed" and add an observation that all outliers have been properly handled.
