This server is marked deprecated in the MCP registry.
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →
Supply Chain Security87
- No malware found by supply-chain analysis.Pass
- Only part of the dependency tree could be resolved (108 of 112), so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- Only part of the dependency tree could be resolved (108 of 112), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency32
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- License check failed: the license (PolyForm-Noncommercial-1.0.0) isn't a recognized OSI-approved license. See how to fix → Fail
- Actively maintained (last published 113 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability77
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 681 tokens (~48/item across 14 items; 14 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

- 3 Aug 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

Dependencies 108 packages
108 packages in the resolved dependency tree · 108 deprecated · 30 stale.
The dependency tree was only partially resolved, so these counts may be incomplete.
The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.
batch_search ~33
Execute up to 5 searches in parallel in one call. Always prefer this over multiple search_code calls for the same investigation.
No input parameters.
No output schema declared.
No examples provided.
browse_directory ~16
List files/subdirectories at a path.
No input parameters.
No output schema declared.
No examples provided.
find_file ~19
Find files by name/path pattern across the codebase.
No input parameters.
No output schema declared.
No examples provided.
get_compile_info ~41
Get compilation details for a source file: compiler, include paths, preprocessor defines, and language standard. Requires compile_commands.json to be present in the workspace.
No input parameters.
No output schema declared.
No examples provided.
get_file_annotate ~29
Blame annotations (who changed each line). Use start_line/end_line to limit output.
No input parameters.
No output schema declared.
No examples provided.
get_file_content ~43
Get file contents. ALWAYS pass start_line/end_line — never fetch full files. Use search_code first to find line numbers. For full symbol context use get_symbol_context.
No input parameters.
No output schema declared.
No examples provided.
get_file_history ~15
Commit history for a file.
No input parameters.
No output schema declared.
No examples provided.

No input parameters.
No output schema declared.
No examples provided.
get_symbol_context ~37
Complete symbol investigation in one call: definition with context + corresponding header + references. Use this first for any unknown C++ symbol or function.
No input parameters.
No output schema declared.
No examples provided.
index_health ~25
OpenGrok server connection status and diagnostics. Call if results seem stale or incomplete.
No input parameters.

No examples provided.
list_projects ~15
List indexed OpenGrok projects.
No input parameters.
No output schema declared.
No examples provided.
search_and_read ~37

No input parameters.
No output schema declared.
No examples provided.
search_code ~53
Search OpenGrok. Types: full (text), defs (definitions), refs (references), path (filenames), hist (commit messages). Prefer defs/refs for known symbol names. Use batch_search for multiple queries.
No input parameters.
No output schema declared.
No examples provided.
search_suggest ~17
