Use when searching code, finding symbols, analyzing call graphs, scanning for security vulnerabilities, exploring dependencies, or performing static analysis on indexed repositories. allowed-tools mcp__narsil-mcp__* Narsil Code Intelligence Narsil is an MCP server providing 90 code intelligence tools (plus 2 prompts: explain_codebase , find_implementation ). This skill helps you use them effectively. Critical: Parameter Naming Use short parameter names . These are the most common mistakes: Wrong Correct repo_path repo symbol_name symbol file_path path function_name function The repo parameter expects the repository name from list_repos , not the full filesystem path. Getting Started Always start with: list_repos → See indexed repositories get_index_status → See which features are enabled Feature Requirements Some tools require specific CLI flags when starting narsil-mcp: Feature Required Flag Tools Git integration --git get_blame, get_file_history, get_recent_changes, get_hotspots, get_contributors, get_commit_diff, get_symbol_history, get_branch_info, get_modified_files Call graph --call-graph get_call_graph, get_callers, get_callees, find_call_path, get_complexity, get_function_hotspots LSP --lsp Enhanced: get_hover_info, get_type_info, go_to_definition Neural search --neural neural_search, get_neural_stats Remote repos --remote (+ GITHUB_TOKEN ) add_remote_repo, list_remote_files, get_remote_file Knowledge graph --graph sparql_query, list_sparql_templates, run_sparql_template, get_ccg_manifest, export_ccg_*, query_ccg, import_ccg, import_ccg_from_registry, get_ccg_acl, get_ccg_access_info If a tool returns empty results or errors, check get_index_status to verify the feature is enabled. Relevant environment variables Var Purpose GITHUB_TOKEN Auth for --remote GitHub API calls EMBEDDING_API_KEY / VOYAGE_API_KEY / OPENAI_API_KEY Neural embedding provider key EMBEDDING_SERVER_ENDPOINT Custom/self-hosted embeddings endpoint RUST_LOG Logging level ( debug , info , warn , error ) Tool Selection Guide Finding Code Task Best Tool When to Use Find files by name find_symbols with file_pattern Know filename pattern Find function/class definitions find_symbols Know symbol type Search by content search_code Keyword search BM25-ranked search semantic_search Better ranking than search_code Semantic code search hybrid_search Natural language queries (combines BM25 + TF-IDF) Find similar code find_similar_code Have a code snippet Find code like a symbol find_similar_to_symbol Find patterns similar to existing function Find code clones find_semantic_clones Detect duplicate/similar code (Type-3/4 clones) Search AST chunks search_chunks Want function/class boundaries Fuzzy symbol search workspace_symbol_search Unsure of exact name Compact codebase manifest get_ccg_manifest AI-context-friendly summary of identity, symbol counts, languages, security posture (requires --graph ) Note: explain_codebase and find_implementation are MCP prompts , not tools. They surface as templates the client can present to the user (or wrap as slash commands), and cannot be called from a tool-calling workflow. Use the tool sequences in the workflow tables below to achieve the same result. Understanding Code Task Best Tool Read a file get_file Read specific lines get_excerpt Get AST chunks for file get_chunks Get function source get_symbol_definition Find all references find_references Find all usages (cross-file) find_symbol_usages See what exports a module has get_export_map Analyze imports/dependencies get_dependencies See what calls a function get_callers See what a function calls get_callees Full call graph get_call_graph Find path between functions find_call_path Function complexity get_complexity Find high-connection functions get_function_hotspots Get type info at position get_hover_info Get precise type info get_type_info Go to definition go_to_definition Security Analysis Task Best Tool Full security scan scan_security Security overview get_security_summary OWASP Top 10 check check_owasp_top10 CWE Top 25 check check_cwe_top25 Find injection flaws find_injection_vulnerabilities Find taint sources get_taint_sources Trace tainted data trace_taint Explain a vulnerability explain_vulnerability Get fix suggestion suggest_fix Check dependencies for CVEs check_dependencies Find upgrade paths find_upgrade_path License compliance check_licenses Generate SBOM generate_sbom Static Analysis Task Best Tool Control flow graph get_control_flow Data flow analysis get_data_flow Reaching definitions get_reaching_definitions Find dead code find_dead_code Find dead stores find_dead_stores Find uninitialized vars find_uninitialized Infer types (Python/JS/TS) infer_types Check type errors check_type_errors Taint flow with types get_typed_taint_flow Import dependency graph get_import_graph Find circular imports find_circular_imports Remote GitHub Repos (requires --remote, GITHUB_TOKEN env) Task Best Tool Clone & index a GitHub repo add_remote_repo List files via GitHub API (no clone) list_remote_files Fetch single file via GitHub API get_remote_file SPARQL Knowledge Graph (requires --graph) Task Best Tool Run a SPARQL query against the RDF graph sparql_query List built-in SPARQL templates list_sparql_templates Run a named SPARQL template with params run_sparql_template Code Context Graph / CCG export (requires --graph) CCG layers ship a portable, layered description of a codebase suitable for AI handoff or external indexing. Task Best Tool Get Layer 0 manifest (~1-2KB JSON-LD) get_ccg_manifest Export Layer 0 manifest to file export_ccg_manifest Export Layer 1 architecture (~10-50KB) export_ccg_architecture Export Layer 2 symbol index (gzipped N-Quads) export_ccg_index Export Layer 3 full detail (gzipped N-Quads) export_ccg_full Export all CCG layers as a bundle export_ccg Run a SPARQL query against a repo's CCG query_ccg Generate WebACL access control file get_ccg_acl Show available CCG access tier info get_ccg_access_info Import a CCG from URL/file import_ccg Import from codecontextgraph.com registry import_ccg_from_registry Git History (requires --git) Task Best Tool Git blame for file get_blame File commit history get_file_history Recent repo changes get_recent_changes High-churn files get_hotspots Contributors to file/repo get_contributors Diff for a commit get_commit_diff Symbol change history get_symbol_history Current branch info get_branch_info Uncommitted changes get_modified_files Utility & Diagnostics Task Best Tool List indexed repos list_repos Get project structure get_project_structure Check enabled features get_index_status Force re-index reindex Discover repos in directory discover_repos Validate repo path validate_repo Incremental index status get_incremental_status Performance metrics get_metrics Embedding stats get_embedding_stats Chunk stats get_chunk_stats Common Patterns Explore a new codebase 1. list_repos → get repo name 2. get_project_structure(repo) → see directory tree 3. find_symbols(repo, symbol_type=\"function\") → see main functions 4. get_import_graph(repo) → understand module structure Find where something is implemented 1. workspace_symbol_search(query=\"feature name\") → find candidates 2. find_symbol_usages(repo, symbol) → see all usages 3. get_symbol_definition(repo, symbol) → read the code Security audit 1. scan_security(repo) → get all findings 2. check_owasp_top10(repo) → check critical vulnerabilities 3. check_dependencies(repo) → find vulnerable dependencies 4. find_injection_vulnerabilities(repo) → focus on injection flaws 5. For each finding: suggest_fix(repo, path, line) → get remediation Understand a function 1. get_symbol_definition(repo, symbol) → read source 2. get_callers(repo, function, transitive=true) → who calls it 3. get_callees(repo, function) → what it calls 4. get_complexity(repo, function) → cyclomatic complexity 5. get_data_flow(repo, path, function) → variable flow Handling Large Results For large codebases, use pagination and filtering: max_results parameter limits output size file_pattern filters by glob (e.g., \"*.py\" , \"src/**/*.ts\" ) severity_threshold filters security findings (critical, high, medium, low) Troubleshooting \"No repository found\" → Run list_repos and use exact repo name Empty results from git tools → Check get_index_status shows git enabled Empty results from call graph → Check get_index_status shows call-graph enabled Slow searches → Use file_pattern to narrow scope For detailed workflow examples, see WORKFLOWS.md .",
