The extension +adds tools, durable jobs, stored results, monitoring, and private proxy profiles. +It uses the core collector for Meta access, parsing, pagination, enrichment, +deduplication, media downloads, filtering, reports, and webhook delivery. + +## Install and connect + +The MCP extra requires Python **3.10 or newer**. The core collector retains its +Python 3.9 support and does not require the MCP SDK. + +For this development version, install from the repository root: + +```bash +python -m pip install -e ".[mcp]" +meta-ads-mcp --help +``` + +Once a release containing the extension is published, the equivalent PyPI +installation is `python -m pip install "meta-ads-collector[mcp]"`. An extra is +an optional dependency group of the same distribution, not a second collector. +The ordinary collector import and CLI retain their existing implementation. + +Configure an MCP client that supports local stdio servers: + +```json +{ + "mcpServers": { + "meta-ads": { + "command": "meta-ads-mcp", + "args": [] + } + } +} +``` + +Use the executable's absolute path if the client does not inherit your Python +environment's PATH. The client launches the server; installation alone does not +start a daemon. Protocol messages use stdout and redacted logs use stderr. + +Default storage is `~/.meta-ads-collector-mcp`. Set `METAADS_MCP_DATA_DIR` or pass +`--data-dir` to choose another directory. Use **the same directory** for your +server and persistent worker. SQLite stores job definitions, results, events, +leases, checkpoints, proxy references, schedules, and monitor observation IDs. + +## Tools + +| Tool | Operations | +| --- | --- | +| `discover` | Supported values, schemas, fields, budgets, coverage, and worker liveness | +| `advertisers` | Page-name candidates or numeric page-ID extraction from supported URLs | +| `search` | Keyword/page searches with supported native parameters and local filters; interactive or background | +| `continue_search` | Another batch from the same search, with native pagination and deduplication | +| `inspect_ads` | Batch inspection, optional detail enrichment, and bounded media downloads | +| `results` | Stored-result pagination, field selection, local filtering, sorting, and newly observed records | +| `export_results` | JSON, JSONL, CSV, and explicitly requested webhook delivery | +| `jobs` | List, status, events, report, cancel, resume, delete | +| `monitoring` | Create, list, enable, disable, delete recurring collection definitions | +| `proxy` | Configure reference profiles, list redacted profiles, select a default, check actual Meta connectivity | + +Resources: `metaads://capabilities` and `metaads://results/{result_set_id}`. +Resources return bounded data; use the tools for pagination and field selection. + +### Search example + +Arguments for the `search` tool: + +```json +{ + "search": { + "query": "nike", + "country": "US", + "status": "ACTIVE", + "page_size": 20, + "max_results": 100, + "max_requests": 20, + "max_seconds": 600 + }, + "batch_size": 20, + "background": false +} +``` + +Keep the returned `result_set_id`. `continue_search` retrieves more evidence; +`results`, `inspect_ads`, and `export_results` reuse that collection. Advertiser +searches may be ambiguous: select the intended numeric ID before searching with +`page_ids`. Numeric IDs in supported Facebook URLs can be resolved directly; +vanity URLs require a name search and are not silently treated as numeric IDs. + +Native parameters include query, country, category, status, search mode, +advertiser IDs and supported sorting. Local filters cover impressions/spend +ranges, delivery **start** date bounds, media type, platforms, languages, and +image/video presence. Discovery lists the exact supported values. + +Range filters use **overlap**, not proof of an exact metric. `missing_data` is +`include` by default; select `exclude` to require the relevant metric bounds, +dates, platform or language data. Missing values never become zero. + +Responses default to summary fields. Request `view="detailed"` for normalized +fields, `view="raw"` for the complete supplied Meta row, or `fields` to select +specific fields. Raw data is preserved through the core's `api_fields` property. +Normalized fields follow the existing core model's defaults; raw `api_fields` +identifies the keys actually supplied by Meta. Ad bodies and links are untrusted +third-party content, not instructions. + +## Background jobs and recovery + +Set `background=true` to queue collection and return without waiting for it to +finish. Inspect its status or events using `jobs`. Events have sequence IDs for +incremental reading. Requests and network concurrency are bounded; core HTTP +retries/bootstrap are separate from the search-page request budget. + +Interactive calls preserve a live native generator between batches. On restart, +the server replays the **last requested page**, reuses saved search tokens where +possible, and skips already committed ads. Saving the next-page cursor alone +would lose ads if a process died halfway through a page. Invalid/expired cursor +responses restart the search with deduplication and report that recovery mode. +Other upstream failures remain explicit failures with partial results retained. + +Jobs have `QUEUED`, `RUNNING`, `PAUSED`, `COMPLETED`, `LIMIT_REACHED`, `FAILED`, +or `CANCELLED` states. Only `COMPLETED` means that this query was exhausted; it +does not prove coverage of every ad on Meta. Resume paused, cancelled or failed +jobs with `jobs(action="resume")`. Original budgets remain in force. + +Workers use renewable leases to prevent duplicate execution. After a hard crash, +another process can reclaim the job once its lease expires (normally within +30 seconds of the last heartbeat). Cancellation and duration limits are checked +at safe boundaries; an in-flight core request can finish before cancellation. +Active duration excludes time waiting between interactive tool calls. + +## Monitoring and the persistent worker + +Create a monitoring schedule containing a name, `search` specification, +`interval_seconds` (at least 60), and `retention_days`. A monitor does not overlap +its own pending run. Missed intervals coalesce into one current collection. +Observation IDs persist across runs; "newly observed" does not mean "launched +since the last run". Retention removes old terminal collections for that monitor. + +A client-launched server stops when the client closes. To run monitoring and +background jobs independently, explicitly start: + +```bash +meta-ads-mcp worker +``` + +The worker remains attached to that terminal. Run it under your operating +system's service/process manager for unattended operation. `worker --once` runs +one scheduling pass and finishes the jobs it starts. It does not loop through +future schedules. Discovery reports persistent-worker liveness. + +## Private proxy and session configuration + +Put proxy URL(s) in a private environment variable inherited by the server and +worker. Do not put passwords in MCP arguments or client configuration examples. +Alternatively, store a proxy file under `/.private/` and reference its +relative filename. Profiles support newline-separated proxies, failure limits +and cooldowns using the existing core `ProxyPool`. + +Arguments for `proxy` after privately setting `METAADS_PROXY`: + +```json +{ + "action": "configure", + "profile": { + "name": "research", + "environment": "METAADS_PROXY", + "max_failures": 3, + "cooldown": 300 + } +} +``` + +Select it with `proxy(action="default", name="research")`, or use +`search.proxy_profile` per job. Profile settings are snapshotted when jobs are +created. Secrets resolve at session start and must be available in a process +that resumes the job. Changing defaults does not alter running sessions. +Provider-specific sticky-session parameters should be included in the private +proxy configuration when the provider rotates residential exits per connection. +`proxy(action="clear_default")` clears the selected profile and returns to the +core collector's environment-based proxy behavior. + +`--proxy-env METAADS_PROXY` configures a startup profile without putting the URL +on the command line. `search.cookie_env` similarly references a private variable +containing the core-supported cookie header. Search timeout, retry, delay and +jitter settings are also available. Credentials are never stored in job records +or returned by discovery/profile listing. Your MCP client may log tool arguments, +which is why these interfaces accept references rather than passwords. + +## Exports, media and webhooks + +Exports use existing stored results and never trigger a fresh Meta search. JSON +includes collection metadata; JSONL and CSV have a metadata sidecar. CSV encodes +nested values, including `api_fields`, as JSON cells. Relative filenames are +confined to `/artifacts`; existing filenames are not overwritten. + +Media downloads delegate to the core downloader with limits on streamed bytes +and requests. Defaults are 64 MiB per file and 256 MiB per inspection batch. +Only Meta-hosted HTTPS asset URLs are accepted. Failed or unavailable downloads +are reported individually. Previously cached files can be reused. + +Webhook delivery is explicit: provide `webhook_environment` to `export_results` +with a private environment-variable reference containing the destination. +Delivery reports successes and failures; export success does not imply webhook +delivery success. Exported files and media remain on disk when SQLite results +are deleted or expire; manage those artifacts separately. + +## Capability coverage and verification + +| Existing core surface | MCP route | +| --- | --- | +| Page search and page ID/URL/name collection | `advertisers`, then `search(page_ids=...)` | +| Sync/async searches and collection | Native sync collector dispatched off the asynchronous MCP event loop | +| Pagination and deduplication | `continue_search`, durable page replay and committed-result tracking | +| Filtering | `search.filters`, `results.filters`; core filtering plus explicit strict-missing policy | +| Enrichment and media collection | `inspect_ads` with optional enrichment/downloads | +| Normalized models and all supplied fields | Detailed/raw views and selected fields | +| JSON/JSONL/CSV collection | `search`, then `export_results` without recollection | +| Streaming events, callbacks and reports | Durable job events and collection reports | +| Webhooks | Explicit export delivery using the core sender | +| Proxy pools, cookies, retries and timeouts | Private profiles and search configuration | + +Run infrastructure, captured-record and actual stdio tests: + +```bash +python -m pip install -e ".[dev,mcp]" +python -m pytest mcp/tests -m "not mcp_live" +``` + +Run real Meta tests (privately configured proxy recommended): + +```bash +python -m pytest mcp/tests -m mcp_live --run-mcp-live +``` + +These checks cover real searches, pagination, all supplied-record preservation, +exports, details, media, stdio restarts, monitoring, and a real worker process +kill followed by lease expiry and recovery. Controlled failure tests supplement +live verification and are clearly labeled; they do not establish connectivity. + +CI runs core regressions, MCP checks on Python 3.10–3.14 and Windows, isolated +wheel installation, and live Meta verification using the private CI proxy. +MCP runtime directories and test evidence are ignored and excluded from +distributions.
