Code Context Provider MCP

by AB498

get_code_context

Analyzes a project directory to generate a comprehensive codebase overview, including directory structure and code symbols. Use to quickly understand project layout and key elements at task initiation.

Instructions

Returns Complete Context of a given project directory, including directory tree, and code symbols. Useful for getting a quick overview of a project. Use this tool when you need to get a comprehensive overview of a project's codebase. Useful at the start of a new task.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
absolutePathYesAbsolute path to the directory to analyze. For windows, it is recommended to use forward slashes to avoid escaping (e.g. C:/Users/username/Documents/project/src)
analyzeJsNoWhether to analyze JavaScript/TypeScript and Python files. Returns the count of functions, variables, classes, imports, and exports in the codebase.
includeSymbolsNoWhether to include code symbols in the response. Returns the code symbols for each file.
maxDepthNoMaximum directory depth for code analysis (default: 5 levels). Directory tree will still be built for all levels. Reduce the depth if you only need a quick overview of the project.
symbolTypeNoType of symbols to include if includeSymbols is true. Otherwise, returns only the directory tree.all

Implementation Reference

  • The main execution handler for the get_code_context tool. Handles input parameters, initializes Tree-sitter if needed for code analysis, generates directory tree and symbol analysis using helper functions, compiles the response.

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It describes what the tool returns (context, directory tree, code symbols) and its usefulness for project overviews, but lacks details on performance, error handling, or specific output format. This provides basic behavioral context but leaves gaps for a tool with 5 parameters.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is appropriately sized with three sentences that each add value: stating the tool's purpose, its usefulness for overviews, and when to use it. It is front-loaded with the core functionality. A minor deduction for slight redundancy ('useful' appears twice).

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (5 parameters, no output schema, no annotations), the description is moderately complete. It covers the purpose and usage context but lacks details on output format, error cases, or performance considerations. Without an output schema, more guidance on return values would be beneficial for full contextual understanding.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema description coverage is 100%, so the schema fully documents all 5 parameters. The description does not add any parameter-specific semantics beyond what the schema provides, such as explaining interactions between parameters like analyzeJs and includeSymbols. The baseline score of 3 reflects adequate but not enhanced parameter understanding.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose with specific verbs ('returns complete context') and resources ('project directory, including directory tree, and code symbols'). It distinguishes the tool's comprehensive overview capability, which is well-defined even without sibling tools for comparison.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context for when to use the tool ('useful for getting a quick overview of a project' and 'useful at the start of a new task'). However, it lacks explicit guidance on when not to use it or alternatives, as there are no sibling tools mentioned to differentiate from.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
