The `deployment` block above describes the one an agent can call right now: the DOCUMENTATION MCP server at https://apidocs.mediamath.com/mcp, which answered an anonymous `tools/list` with HTTP 200 on 2026-08-13 and returned six real tools with full inputSchemas. Its `initialize` handshake reports serverInfo.name "Infillion API Docs", version "2026-08-13", protocolVersion "2025-06-18". No credentials were needed. The second surface — the Infillion Agent Connector, the actual media-buying execution layer with 60+ tools — is REMOTE and SSE-based but its endpoint URL is NOT published: the provider's own docs say the URL is handed out individually during closed-beta onboarding. No endpoint is recorded for it below, and none was guessed. servers: - name: Infillion API Docs MCP kind: documentation status: published mode: remote endpoint: https://apidocs.mediamath.com/mcp transport: streamable-http (SSE responses; Accept application/json, text/event-stream) auth: none protocol_version: '2025-06-18' server_info: name: Infillion API Docs version: '2026-08-13' verified: probed probe: method: POST body: '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' http_status: 200 fetched: '2026-08-13' tools_returned: 6 tools_file: mediamath-docs-mcp-tools.json tools: - name: list-apis description: Lists available APIs with their context and purpose read_only: true - name: get-endpoints description: Get all endpoints for a specific API read_only: true - name: get-endpoint-info description: Get comprehensive information about specific endpoint including parameters, security, and examples read_only: true - name: get-security-schemes description: Get the security schemes for a specific API read_only: true - name: get-full-api-description description: Get the complete OpenAPI description read_only: true - name: search description: Search across the documentation to fetch relevant content for a given query read_only: true note: >- This server is the reason seven previously-uncaptured MediaMath OpenAPI definitions are now in openapi/. `list-apis` enumerates nine published APIs and `get-full-api-description` returns each one's complete OpenAPI 3.0.0 document. The docs host renders client-side and serves an HTML shell for /openapi.json, so the MCP server is currently the only machine-readable route to those contracts. The authorization server that fronts it is recorded at well-known/mediamath-oauth-authorization-server.json; it is advertised but not enforced on tools/list. - name: Infillion Agent Connector kind: execution status: closed-beta mode: remote endpoint: null transport: SSE auth: platform-credentials verified: searched docs: https://apidocs.mediamath.com/guides/mcp/overview product_page: https://infillion.com/infillion-agent-connector/ announcement: https://infillion.com/blog/infillion-launches-infillion-agent-connector-a-new-way-of-managing-ai-controlled-buying-that-runs-on-the-first-agent-native-composable-platform-in-adtech/ tool_count_documented: 69 tool_count_claimed: '60+' note: >- Endpoint deliberately left null. The provider states the server URL is "provided during onboarding" by a Client Services representative and the published Claude Desktop config example uses the literal placeholder . No URL was guessed and no endpoint was probed for this server. Authentication is described as handled inside the MCP handshake using the caller's MediaMath Platform credentials — no separate API key or OAuth2 client registration — and all operations inherit the calling user's existing platform permissions, with no privilege escalation path. tool_categories: - name: Organization & Entity Management tools: [find_organizations, get_organization_info, find_agencies, get_agency_info, find_advertisers, get_advertiser_info] - name: Campaign Management tools: [find_campaigns, get_campaign_info, campaign_create, campaign_update] - name: Strategy Management tools: [find_strategies, get_strategy_info, strategy_create, strategy_update] - name: Concepts (Creative Groups) tools: [find_concepts, get_concept_info, creative_group_create] - name: Creative Management tools: [find_atomic_creatives, get_atomic_creative_info, get_atomic_creative_preview, atomic_creative_create, atomic_creative_update, atomic_creative_healthcheck, mmas_creative_upload, mmas_creative_video_upload, find_native_creatives, get_native_creative_info, native_creative_create, native_creative_update, get_native_creative_approvals, get_video_creative_info, list_video_creatives, video_creative_create, video_creative_update, video_creative_bulk_create, video_creative_bulk_update] - name: Inventory & Supply tools: [find_supply_sources, get_supply_source_info, find_site_lists, get_site_list_info, site_list_create, site_list_update, find_publishers, find_target_values, get_channels_info, find_deals, get_deal_info, deal_create, deal_update, find_deal_strategies, find_deal_groups, get_deal_group_info, deal_group_create, deal_group_update] - name: Pixels & Tracking tools: [find_pixel_bundles, get_pixel_bundle_info, get_pixel_providers] - name: Audience & Data tools: [find_audience_segments, find_contextual_segments] - name: Reporting & Analytics tools: [get_dataset_schema, query_performance_report, query_hourly_performance_report, query_all_dimensions_report, query_win_loss_report, query_pixel_loads_report] - name: User & Permissions tools: [find_user, get_user_info, get_user_permissions] - name: System tools: [healthcheck] ui_resources: - uri: ui://display-creative-upload note: MCP App form opened by mmas_creative_upload when no public file URL is supplied. - uri: ui://video-creative-upload note: MCP App form opened by mmas_creative_video_upload when no public file URL is supplied. conventions: naming: >- find_* for search/discovery, get_*_info for detailed inspection, *_create / *_update for mutations. Documented workflow shape is Discover -> Inspect -> Act. pagination: find_campaigns returns up to 25 results per call and paginates. response_modes: find_* tools accept full=true and extended=true for richer payloads. limitations: - The Agent Connector tool list is transcribed from the provider's published Tool Reference. Input schemas were NOT captured because the server is not publicly reachable — a live tools/list against the beta endpoint is required to record real inputSchema objects. - The provider warns that the Tool Reference lags the deployed tool set and that agents should re-discover tools on each connection, so this list is a snapshot.
