Before you install Contextplus

AgenticMart scanned Contextplus on Nov 5, 2026 with automated checks for hidden code, known-malicious packages, leaked secrets and vulnerable dependencies. The result covers one commit under our scan policy, so review what access you give it and check any advisories shown here.

What it can access

  • An MCP server is a program your AI app starts and talks to. A local one runs with your user's permissions: it can see the files, environment variables and network your account can.

Before you install

  1. Pin the version you reviewed instead of always installing the latest release.
  2. Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.
  • Maintained by forloopcodes on GitHub, 1,988 stars and 169 forks. Popularity is not proof of safety.
  • Last code change: Jul 13, 2026.
  • Open-source license: MIT.

Tools Contextplus exposes (17)

Listed by the server itself during our scan of commit 1b59b37.

  • get_context_tree

    Get the structural tree of the project with file headers, function names, classes, enums, and line ranges. Automatically reads 2-line headers for file purpose. Dynamic token-aware pruning: Level 2 (deep symbols) -> Level 1 (headers only) -> Level 0 (file names only) based on project size.

  • semantic_identifier_search

    Search semantic intent at identifier level (functions, methods, classes, variables) with definition lines and ranked call sites. Uses embeddings over symbol signatures and source context, then returns line-numbered definition/call chains.

  • get_file_skeleton

    Get detailed function signatures, class methods, and type definitions of a specific file WITHOUT reading the full body. Shows the API surface: function names, parameters, return types, and line ranges. Perfect for understanding how to use code without loading it all.

  • semantic_code_search

    Search the codebase by MEANING, not just exact variable names. Uses Ollama embeddings over file headers and symbol names. Example: searching 'user authentication' finds files about login, sessions, JWT even if those exact words aren't used, with matched definition lines.

  • get_blast_radius

    Before deleting or modifying code, check the BLAST RADIUS. Traces every file and line where a specific symbol (function, class, variable) is imported or used. Prevents orphaned code. Also warns if usage count is low (candidate for inlining).

  • run_static_analysis

    Run the project's native linter/compiler to find unused variables, dead code, type errors, and syntax issues. Delegates detection to deterministic tools instead of LLM guessing. Supports TypeScript, Python, Rust, Go.

  • propose_commit

    The ONLY way to write code. Validates the code against strict rules before saving: 2-line header comments, no inline comments, max nesting depth, max file length. Creates a shadow restore point before writing. REJECTS code that violates formatting rules.

  • list_restore_points

    List all shadow restore points created by propose_commit. Each point captures the file state before the AI made changes. Use this to find a restore point ID for undoing a bad change.

  • undo_change

    Restore files to their state before a specific AI change. Uses the shadow restore point system. Does NOT affect git history. Call list_restore_points first to find the point ID.

  • semantic_navigate

    Browse the codebase by MEANING, not directory structure. Uses spectral clustering on Ollama embeddings to group semantically related files into labeled clusters. Inspired by Gabriella Gonzalez's semantic navigator. Requires Ollama running with an embedding model and a chat model for labeling.

  • get_feature_hub

    Obsidian-style feature hub navigator. Hub files are .md files containing [[path/to/file]] wikilinks that act as a Map of Content. Modes: (1) No args = list all hubs, (2) hub_path or feature_name = show hub with bundled skeletons of all linked files, (3) show_orphans = find files not linked to any hu

  • upsert_memory_node

    Create or update a memory node in the linking graph. Nodes represent concepts, files, symbols, or notes with auto-generated embeddings. If a node with the same label and type exists, it updates content and increments access count. Returns the node ID for use in create_relation.

  • create_relation

    Create a typed edge between two memory nodes. Supports relation types: relates_to, depends_on, implements, references, similar_to, contains. Edges have weights (0-1) that decay over time via e^(-λt). Duplicate edges update weight instead of creating new ones.

  • search_memory_graph

    Search the memory graph by meaning with graph traversal. First finds direct matches via embedding similarity, then traverses 1st/2nd-degree neighbors to discover linked context. Returns both direct hits and graph-connected neighbors with relevance scores.

  • prune_stale_links

    Remove stale memory graph edges whose weight has decayed below threshold via e^(-λt) formula. Also removes orphan nodes with no edges, low access count, and >7 days since last access. Keeps the graph lean.

  • add_interlinked_context

    Bulk-add multiple memory nodes with automatic similarity linking. Computes embeddings for all items, then creates similarity edges between any pair (new-to-new and new-to-existing) with cosine similarity ≥ 0.72. Ideal for importing related concepts, files, or notes at once.

  • retrieve_with_traversal

    Start from a specific memory node and traverse the graph outward. Returns the starting node plus all reachable neighbors within the depth limit, scored by edge weight decay and depth penalty. Use after search_memory_graph to explore a specific node's neighborhood.
