Loading the registry…
Tako MCP grounds your agent in two kinds of knowledge at once: proprietary structured data from trusted providers, and full web search. The curated side covers company financials, macroeconomic indicators, web and app traffic, sports, US government spending, and more. One tool call returns typed values with named sources when curated data exists, and agent-ready web results and page text for everything else. That combination is the point. A pure data API misses most questions, and a pure web search API makes your agent do the reading.
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
17 critical findings reported by cisco-skill-scanner, agent-audit-kit, 11 of them in the installed artifact. The composite score alone does not reflect this — read the per-scanner reports below.
Choose your runtime: the CLI writes the mcpServers config entry for that target.
nerlo install --target claude-code -- tako
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
4 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Flagged badge are computed from those raw severities alone. Nothing below moved them.
Out of 295 findings across every scanner that examined this package. 6 of 17 findings rated critical by their scanner were among the dismissals.
Two keys had to turn. The model had to name a reason from a fixed list of six, and a deterministic check of ours — over which files this artifact actually installs — had to independently agree. Anything it could not corroborate is in “not reviewed” above, at full severity.
130 Test or fixture file — The match is in a test or fixture. Our own check confirmed the file is not part of what gets installed.
Rules: YARA_coercive_injection_generic, COMMAND_INJECTION_JS_FUNCTION_CONSTRUCTOR, AAK-MCP-APPS-001 and 10 more · Files: /repo/workers/src/embed_proxy.test.ts, workers/test/widget/chatgpt-diagnostic.test.ts, workers/test/widget/widget-dom.test.ts and 15 more · reported by cisco-skill-scanner, agent-audit-kit
4 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.
Rules: SOCIAL_ENG_VAGUE_DESCRIPTION, MANIFEST_MISSING_LICENSE · Files: /repo/docs/SKILL.md, /repo/docs/gemini/SKILL.md · reported by cisco-skill-scanner
3 CI or editor configuration — The match is in build, CI or editor configuration, confirmed by our own check to be outside the installed artifact.

2 Agent instruction file — The match is in a file that instructs an AI coding agent — a CLAUDE.md or similar. It is documentation of intent, and our own check confirmed it is not part of what gets installed.
Rules: AAK-AGENT-002 · Files: AGENTS.md · reported by agent-audit-kit
These findings are in files this artifact installs and are not placeholder values. No false-positive basis can be corroborated for such a finding, so this review never dismisses one; they were not sent to the model and stand at their scanner's severity.

1 AAK-MCP-CARD-003
Files: registry/server.json · reported by agent-audit-kit
Critical vulnerabilities found, including command injection and SSRF.
The artifact exhibits critical command injection capabilities in `workers/src/mcp.ts` and generic injection in `workers/src/embed_proxy.ts`. It also contains critical Server-Side Request Forgery (SSRF) vulnerabilities in `workers/src/mcp.ts` and `workers/src/tools/types.ts`, allowing it to make requests to arbitrary network locations. Additionally, DNS rebinding issues are present in `workers/scripts/golden.ts`, `panel.ts`, and `smoke.ts`, which could bypass network controls. High severity findings indicate secrets are used in network egress operations across multiple worker scripts.
Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
