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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog) Scored 2026-10-16. - **Supply Chain Security**: 0/100 - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package. - Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read. - Install-script risk not yet assessed. - Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read. - **Provenance & Transparency**: 100/100 - Source repository is publicly reachable at the declared URL. - Cryptographically verified build provenance (signed, bound to basitalisandhu/dev-mcp-servers). - Clear OSI-approved license (MIT). - Actively maintained (last published 2 days ago). - Publishes a security disclosure policy (SECURITY.md). - **Schema Quality & AI Usability**: 70/100 - AI-judged instruction clarity (good). - Context-footprint check failed: tool/resource definitions use about 527 tokens (~175/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 0/100 - Stability not yet verified: not enough scan history yet (needs a 30-day window). - **Tool Coverage**: 94/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 83% of tool parameters carry a description. - **Tool Safety**: 75/100 - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured. - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "check_url_headers" implies "send" and declares readOnlyHint instead, contradicting what its own name says it does. - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it. - **Capabilities**: 100/100 - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28. **Unverified: 2 categories.** Categories scored 0 because we could not verify them: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm. ## Install ### How do I install the Security Headers MCP server? Security Headers runs locally as a container image, launched with docker run --rm -i ghcr.io/basitalisandhu/mcp-security-headers:0.2.1. Ready-made configuration for Claude, Cursor, VS Code, Codex and 3 more is on this page, copied from each client's own documentation. ### Claude ```bash claude mcp add basitalisandhu-mcp-security-headers -- docker run --rm -i ghcr.io/basitalisandhu/mcp-security-headers:0.2.1 ``` ### Cursor ```json { "mcpServers": { "basitalisandhu-mcp-security-headers": { "command": "docker", "args": [ "run", "--rm", "-i", "ghcr.io/basitalisandhu/mcp-security-headers:0.2.1" ] } } } ``` ### VS Code ```json { "servers": { "basitalisandhu-mcp-security-headers": { "command": "docker", "args": [ "run", "--rm", "-i", "ghcr.io/basitalisandhu/mcp-security-headers:0.2.1" ] } } } ``` ### Codex ```bash codex mcp add basitalisandhu-mcp-security-headers -- docker run --rm -i ghcr.io/basitalisandhu/mcp-security-headers:0.2.1 ``` ### opencode ```json { "$schema": "https://opencode.ai/config.json", "mcp": { "basitalisandhu-mcp-security-headers": { "type": "local", "command": [ "docker", "run", "--rm", "-i", "ghcr.io/basitalisandhu/mcp-security-headers:0.2.1" ], "enabled": true } } } ``` ### Hermes ```yaml mcp_servers: basitalisandhu-mcp-security-headers: command: "docker" args: ["run", "--rm", "-i", "ghcr.io/basitalisandhu/mcp-security-headers:0.2.1"] ``` ### Netclaw ```json { "McpServers": { "basitalisandhu-mcp-security-headers": { "Transport": "stdio", "Command": "docker", "Arguments": [ "run", "--rm", "-i", "ghcr.io/basitalisandhu/mcp-security-headers:0.2.1" ] } } } ``` ### Other ```json { "mcpServers": { "basitalisandhu-mcp-security-headers": { "command": "docker", "args": [ "run", "--rm", "-i", "ghcr.io/basitalisandhu/mcp-security-headers:0.2.1" ] } } } ``` ## Changelog Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims. ### 2026-10-14 (score 49, +29) - [security improvement] Injection markers: unverified → pass - [security] First check of Judged manipulation: pass - [security] Stability: Stability not yet verified: not enough scan history yet (needs a 30-day window). - [functional improvement] Tool coverage: unverified → 100 - [functional improvement] MCP protocol: unverified → pass - [functional] First check of Schema quality: fail - [functional] First check of Tool coverage: 83 - [functional] First check of Schema quality: fail - [functional] First check of Destructive annotations: 0 - [functional] First check of Schema quality: good ### 2026-10-13 (score 20, 0) - [functional] Package version: 0.2.0 → 0.2.1 ### 2026-10-12 (score 20, 0) - [functional] Package version: 0.1.1 → 0.2.0 ### 2026-10-07 (score 20) First indexed and scored. ## MCP tools (3) ### `check_url_headers` (~173 tokens) Fetch and grade a URL's security headers Send a HEAD request (GET when the server answers 405 or 501, or when method is GET) to a public http or https URL, follow up to max_redirects redirects (default 5) and grade the final response's security headers. Returns the final URL, status, redirect chain, every response header, and per-header pass/warn/fail/info checks with explanations, recommendations and an overall grade from A+ to F. Refuses URLs whose host is localhost, a .local or .internal name, or resolves to a private, loopback, link-local or cloud-metadata address. The response body is never downloaded. Input parameters: - `max_redirects` (integer): Default 5. - `method` (string): Default HEAD. - `url` (string, required): Absolute http:// or https:// URL. ### `grade_headers` (~100 tokens) Grade a supplied header set Grade response headers you already have, without any network access. Pass headers as an object of name to value (names are case-insensitive; Set-Cookie may be an array). Returns the same per-header checks and overall grade as check_url_headers. Set https to false when the response came over plain HTTP. Input parameters: - `headers` (object, required): Response headers, name to value. - `https` (boolean): Whether the response was served over HTTPS. Default true. ### `explain_header` (~83 tokens) Explain a security header Describe what one response header does, the recommended value and a reference link. Headers: content-security-policy, strict-transport-security, x-frame-options, x-content-type-options, referrer-policy, permissions-policy, cross-origin-opener-policy, cross-origin-resource-policy, x-xss-protection, server, x-powered-by, set-cookie. Input parameters: - `header` (string, required) ## Diagnostics Captured diagnostic sections: Provenance.

Security Headers is an MCP server listed in the public MCP registry as io.github.basitalisandhu/mcp-security-headers. Fetch a URL's response headers and grade CSP, HSTS, X-Frame-Options and related security headers. This page covers its container image (ghcr.io/basitalisandhu/mcp-security-headers). ### Is the Security Headers MCP server safe to use? Security Headers scores 49 out of 100 on VerifyMCP. 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 Security Headers MCP server expose? Security Headers exposes 3 tools: check_url_headers, grade_headers, explain_header. Their descriptions and schemas cost roughly 356 tokens of context every time the server is loaded. ### Is the Security Headers MCP server still maintained? Security Headers is still listed as active in the MCP registry. We last reached this channel on 16 October 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 Security Headers MCP server under? Security Headers declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls. ## Links - GitHub Container Registry: https://ghcr.io/basitalisandhu/mcp-security-headers - Repository: https://github.com/basitalisandhu/dev-mcp-servers - Website: https://basitalisandhu.github.io/dev-mcp-servers/ - Changelog RSS feed: https://verifymcp.io/servers/basitalisandhu-mcp-security-headers/ghcr-io-basitalisandhu-mcp-security-headers.xml - Changelog JSON feed: https://verifymcp.io/servers/basitalisandhu-mcp-security-headers/ghcr-io-basitalisandhu-mcp-security-headers.json - HTML version of this page: https://verifymcp.io/servers/basitalisandhu-mcp-security-headers/ghcr-io-basitalisandhu-mcp-security-headers
