Category Security
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 → Why this is hard to score →
Supply Chain Security100
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Runs setuptools.build_meta at install time, a recognised build step with no custom scripting around it. View diagnostics → Pass
- 1 of 31 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency100
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to nagameTW/mcp-server-malcolm). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 23 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability77
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 19773 tokens (~373/item across 53 items; 51 tools + 2 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 51 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 53 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
search_dsl Run OpenSearch DSL query ~483
Run a raw OpenSearch DSL query and return its hits plus aggregations. Use this for full DSL control over the query and aggregation bodies. When you only need a match count and not the documents, use count. For Malcolm's simpler field-filter syntax instead of raw DSL, use malcolm_search. Aggregations honor the time filter inside the DSL body, so there is no hidden default time window. Returns the raw OpenSearch _search response. A body OpenSearch rejects comes back as an error carrying OpenSearch's own reason, e.g. a parsing_exception naming the unknown query type. A reply from only some shards, or one that timed out, still arrives as success, so an "INCOMPLETE:" line above the JSON says so; treat its counts as a floor. Every input guard runs before any request leaves this server: malformed query_dsl, an index containing /, ? or .., and a terms, multi_terms, significant_terms, significant_text or composite aggregation (nested ones included) whose size is above 500 are refused as input errors rather than costing an upstream scan. That is the same per-level bucket limit malcolm_aggregate has; for more values than that, page with a composite aggregation's after_key. When the query is easier to say as an Arkime expression, compile it with arkime_build_query and hand the index and query_dsl it returns straight to this tool — serialise its query_dsl object to a JSON string first, which is what this parameter declares.
| Name | Type | Req | Description |
|---|---|---|---|
| index | string | yes | Index or pattern to query, e.g. "arkime_sessions3-*". Accepts a wildcard; must contain no path metachars (/, ?, ..). |
| query_dsl | string | yes | JSON string of a full DSL body, e.g. {"query": {...}, "aggs": {...}}. A bare query clause such as {"term": {...}} is wrapped as {"query": ...} for you; a body with "aggs", "size", "sort" or another s… |

What is the io.github.nagameTW/mcp-server-malcolm server?
io.github.nagameTW/mcp-server-malcolm is listed in the public MCP registry as io.github.nagameTW/mcp-server-malcolm. MCP server for Malcolm (Zeek/Suricata/Arkime/OpenSearch): threat-hunting access for AI agents. This page covers its PyPI package (mcp-server-malcolm).
Is the io.github.nagameTW/mcp-server-malcolm server safe to use?
io.github.nagameTW/mcp-server-malcolm scores 96 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the io.github.nagameTW/mcp-server-malcolm server expose?
io.github.nagameTW/mcp-server-malcolm exposes 51 tools: search_dsl, count, list_indices, index_mapping, cluster_health, and 46 more. Their descriptions and schemas cost roughly 18,657 tokens of context every time the server is loaded.
Is the io.github.nagameTW/mcp-server-malcolm server still maintained?
io.github.nagameTW/mcp-server-malcolm is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
What licence is the io.github.nagameTW/mcp-server-malcolm server under?
io.github.nagameTW/mcp-server-malcolm declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
What did VerifyMCP test on the io.github.nagameTW/mcp-server-malcolm server?
VerifyMCP ran 16 checks on io.github.nagameTW/mcp-server-malcolm, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to a PyPI package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
