Camoufox MCP Server

by whit3rabbit

browse_sequence

Navigate to a URL, run bounded selector actions like clicks and fills, then retrieve the final page state for privacy-focused web automation.

Instructions

Navigate once, run bounded selector actions, then return final state.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
osNoOptional OS to spoof. Can be 'windows', 'macos', or 'linux'. If not specified, will rotate between all OS types.
urlYesThe URL to navigate to. Must be a fully qualified http or https URL.
argsNoAdditional browser command-line arguments to pass to the browser. Rejected unless CAMOUFOX_MCP_ALLOW_UNSAFE_OPTIONS=1; denied args are always rejected.
geoipNoAutomatically detect geolocation based on IP address.
proxyNoProxy configuration for routing browser traffic through an HTTP(S) proxy. Proxy servers are checked against the same local-network URL policy as page requests.
localeNoBrowser locale (e.g., 'en-US', 'fr-FR').
windowNoSet fixed window size [width, height] instead of random generation. An empty array [] is accepted and treated as if the window parameter was not specified.
actionsYesBounded action sequence to run after navigation.
timeoutNoTimeout in milliseconds for page load (5-300 seconds).
headlessNoRun browser in headless mode. Auto-detects best mode for environment if not specified.
humanizeNoEnable realistic cursor movements and human-like behavior for better stealth and anti-detection.
maxCharsNoMaximum final text, HTML, snapshot, or evaluate-result characters to return.
selectorNoOptional CSS selector to limit final content extraction to one matching element.
viewportNoCustom viewport dimensions.
outputModeNoFinal response content mode.text
screenshotNoCapture a screenshot/image after all actions finish.
block_webglNoBlock WebGL to prevent fingerprinting and tracking.
maxElementsNoMaximum final snapshot elements to return.
block_imagesNoBlock all images for faster loading, reduced bandwidth, and lightweight browsing.
block_webrtcNoBlock WebRTC entirely for enhanced privacy and stealth.
disable_coopNoDisable Cross-Origin-Opener-Policy for sites that require it.
enable_cacheNoCache pages, requests, etc. Uses more memory but improves performance when revisiting pages.
waitStrategyNoWait strategy for page load. Defaults to 'domcontentloaded'. 'load' waits for all resources, 'networkidle' waits for network activity to finish.domcontentloaded
captchaPolicyNoChallenge handling policy. 'detect' reports signals, 'pause' returns state for human action, 'fail' returns an error, 'attempt' returns enhanced challenge metadata, interactive elements, a bounded screenshot, and a suggested strategy. When CAPTCHA_AUTONOMOUS=true, responses are marked for LLM-assisted handling and include provider-specific challengePlaybook context when known.
exclude_addonsNoList of default addons to exclude (e.g., ['ublock_origin']). Rejected unless CAMOUFOX_MCP_ALLOW_UNSAFE_OPTIONS=1.
includeConsoleNoInclude bounded page console diagnostics in the JSON response.
includeNetworkNoInclude bounded network diagnostics in the JSON response.
stealthProfileNoConvenience profile for common Camoufox browser settings. Explicit options override profile values.normal
screenshotOptionsNoOptional screenshot capture settings. Used only when screenshot is true.
firefox_user_prefsNoCustom Firefox user preferences to set. Rejected unless CAMOUFOX_MCP_ALLOW_UNSAFE_OPTIONS=1; denied prefs are always rejected.

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already indicate readOnly=false, openWorld=true, idempotent=false, destructive=false. The description adds 'bounded' actions and 'final state' but does not disclose side effects like cookies, challenge handling, or failure behavior. It is consistent with annotations but adds limited extra context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single, front-loaded sentence communicates the core workflow without wasted words. Every phrase contributes meaning.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the very detailed schema and output schema, the high-level description captures the essential workflow. It does not explain every option, but that is handled by the schema. The description could mention session alternatives, but for a bounded one-off sequence it is sufficiently complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and all parameters have descriptions. The description does not add parameter-level detail beyond the schema, so baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's function: navigate once, execute bounded selector actions, and return final state. It distinguishes itself from sibling tools like browse_session_action and browse by emphasizing a single navigation with a bounded action sequence.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'Navigate once' implies a one-shot use case, but it does not explicitly state when to prefer this over browse_session_* or browse. No alternative tools are named or exclusions given, so usage context is only implied.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
