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 →

MCP tools · 17 exposed · ~1,227 tokens

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 →

Tool Tokens
execute_webmcp_tool ~175

Execute one live WebMCP tool in the user-selected active visible Chrome/Brave tab. Use the tab and generation values from list_webmcp_tools. If execution fails because the tab is not eligible or available, call focus_webmcp_tab with the target tabId, then retry. Registry-injected package tools retain their existing confirmation behavior. An execution-timeout error means the call may still have run - verify its effect before retrying. A dispatch-failed error confirms that the call did not run and can be retried.

Inspect the macOS Chrome or Brave WebMCP Today bridge installation without changing files. Reports bridge-owned paths and permissions but never returns the bridge secret.

NameTypeReqDescription

No output schema declared.

No examples provided.

install_package ~109

Pin a package to its latest version, or a given versionId, on your webmcp.today account — creates the pin if absent, moves it if present (also how rollback works: pass an older versionId). This does not install into your browser; the extension's installs are local to the browser. Returns a link that installs this exact version there. Requires an API key.

NameTypeReqDescription

No output schema declared.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

list_installs ~28

No output schema declared.

No examples provided.

publish_package_version ~139

Publish the next version of a package you contributed (urlPatterns, tools, required api and minEngine, optional changelog) — owner only, append-only. The version field is author-declared and must equal the current latest version + 1 exactly (query the package first to see it); a 409 response returns the expectedVersion to declare on retry. Installed users stay pinned until they move their install pin. Requires an API key.

NameTypeReqDescription

NameTypeReqDescription
idstringyesPackage id

No output schema declared.

No examples provided.

uninstall_webmcp_bridge ~82

Remove WebMCP Today's macOS native-messaging bridge artifacts for Chrome or Brave. Brave retains Chrome's compatibility manifest because Brave may use it; the result reports that residual and the required follow-up Chrome uninstall. Set confirm to true to approve removal.

NameTypeReqDescription
browserstring––
confirmboolean–Must be true to approve bridge removal.

No output schema declared.

No examples provided.

update_package_meta ~67

Common questions

What is the WebMCP Today MCP server?

WebMCP Today is an MCP server listed in the public MCP registry as io.github.robertn702/webmcp-today. Your agent gets trustworthy tools on sites without WebMCP, data-only packages you approve. This page covers its npm package (@webmcp-today/mcp-bridge).

Is the WebMCP Today MCP server safe to use?

WebMCP Today scores 91 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 21 September 2026. It declares no install or post-install scripts. 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 WebMCP Today MCP server expose?

WebMCP Today exposes 17 tools: lookup_package, list_packages, get_package, list_installs, get_stats, and 12 more. Their descriptions and schemas cost roughly 1,227 tokens of context every time the server is loaded.

Is the WebMCP Today MCP server still maintained?

WebMCP Today is still listed as active in the MCP registry. We last reached this channel on 21 September 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 WebMCP Today MCP server under?

WebMCP Today declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
