io.github.singleflo/evolution-api-mcpv1.0.0Chat & Messaging

Operate one Evolution API (WhatsApp) instance: chats, history, sending, groups, settings.

The current version, v1.0.0, was published to the official MCP registry on 2026-10-07. It is distributed as evolution-api-mcp on PyPI and as a hosted remote over streamable-http, filed under Chat & Messaging by this index, and declares 11 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.

Using io.github.singleflo/evolution-api-mcp in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Limits of this verdict

- Semantic screen only - the deterministic conformance probe has not run on this server
- Confidence is reported but not yet calibrated (v1)
- Screen reads the tool description, not the live behavior
- advisory
- registry description only no input schema
- screen model 8b

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

Own this server? Test a description on the public screen → It is a separate check from the verdict above, so the two can differ.

That verdict was true at screening time (snapshot 2026-10-24).

Contracts can change after screening, with no version bump. The gate pins io.github.singleflo/evolution-api-mcp’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Cite this record

People vet a server before wiring it in. One line on your project site or docs answers that with an independent record: screening verdict, registry provenance, contract drift history. It stays current as new screens and drift events land.

Environment variables

EVOLUTION_API_URL

required

URL of your Evolution API server (e.g. https://evolution.example.com). Evolution API 2.x is required.

EVOLUTION_INSTANCE_TOKEN

requiredsecret

The token of this one instance (Evolution Manager: open the instance and copy its token). The server's global AUTHENTICATION_API_KEY is refused. The instance name and integration are discovered from the token.

EVOLUTION_MCP_TOOLSETS

Toolsets to enable: a comma list of instance, messaging, chats, contacts, groups, labels, profile, status, catalog, templates, settings, events, integrations, or the presets `core` and `all`. Default: `core` (messaging, chats, contacts). The --toolsets option overrides it.

EVOLUTION_MCP_ALLOW

Tools that change data the agent may call. `*` (default) allows every tool not denied; `none` makes the server read-only; or a comma list of tool names. Reads are never gated by this list.

EVOLUTION_MCP_DENY

Tool names the agent may never call. A value set here REPLACES the default list, which is post_status, remove_group_participants, set_webhook, set_event_channel, set_proxy, set_chatwoot_config.

EVOLUTION_MCP_ALLOW_IRREVERSIBLE

Tools that cannot be undone (logout_instance, delete_message_for_everyone, leave_group, delete_template, delete_chatbot, delete_openai_credential) run only when this is `yes` (also `true` or `1`). Default: no.

EVOLUTION_MCP_DEFAULT_DELAY_MS

Milliseconds of 'typing...' Evolution shows before each message is sent when a call gives no delay. Integer from 0 to 20000. Default: 1200.

EVOLUTION_MCP_MAX_WRITES_PER_MINUTE

Maximum number of tools that change data per minute on this server; 0 turns the limit off. Integer, 0 or more. Default: 30.

EVOLUTION_MCP_FILE_ROOTS

Folders send_local_files may read: absolute paths of existing directories separated by the operating system's path separator (':' on macOS and Linux, ';' on Windows). Default: Desktop, Documents, Downloads, Pictures, Movies and Music in the home folder (those that exist) plus the download folder.

EVOLUTION_MCP_DOWNLOAD_DIR

Absolute folder where download_message_media saves received files and export_chat its exports/ folders. Default: ~/Downloads/evolution-api-mcp.

EVOLUTION_MCP_TIMEZONE

IANA time zone for the times tools show and for times given without a zone, e.g. Europe/Rome. Default: the computer's zone (TZ, then /etc/localtime), else UTC.

Provenance

Each verdict is bound to a hash of the exact description it judged, so a re-crawl that changes the text produces a new record rather than silently inheriting this one. Verdict history is hash-chained and anchored to Bitcoin via OpenTimestamps (latest confirmed at block 972,713). Verify it yourself.
