How to choose
- Permissions and OAuth scopeCheck that the agent acts with the permissions of the person who authorised it, since OAuth grants can reach far more of the organisation than one task needs.
- Message size and pagingCheck the message size limit and how results are paged, because an agent that reads a long channel or thread may need many calls to see the full history.
- Change events without pollingCheck whether change events reach the agent without polling, since an agent that polls a tracker for new tickets adds load and reacts late to updates.
- Deprecation and release policyRead the deprecation policy and release notes, because an agent that calls a deprecated endpoint can break without warning when the service changes its API.
Each one in detail
Mattermost
B 65.8/100Mattermost is an open-core team chat server from Mattermost, Inc. that its owner hosts, with channels, threads, calls and playbooks. Agents reach it through the REST API v4, bot accounts, personal access tokens, webhooks and an MCP server.
Verdict The REST API v4 has a public OpenAPI source of about 600 operations, a dated changelog with API changes per release, and 16 server releases in 90 days. Personal access tokens have no scopes or expiry, paid editions have no public price, and 52 dot releases in twelve months carried security fixes, three of them rated critical.
Choose it for A team that runs its own chat server and wants an agent to read channels, post, search and manage members through a bot account, including in air-gapped networks.
Strengths
- Public OpenAPI 3.0 source for API v4, every operation described, 548 of 604 stating the permission needed
- Sixteen server releases between 11 July and 8 October 2026, each with a dated changelog entry and an API changes list
- Team Edition is free under MIT as a compiled binary, and the free Entry edition needs no card or vendor account
Weaknesses
- Personal access tokens have no scopes and no expiry. A token does whatever its account can do
- 52 dot releases from 28 October 2025 to 8 October 2026 carried security fixes, three rated critical and 21 including high-severity fixes
- No public price for Professional, Enterprise or Enterprise Advanced, and Mattermost Cloud is sold through sales only

Microsoft Teams (Microsoft Graph)
B 62.2/100Microsoft Graph endpoints for Microsoft Teams. An app lists teams, channels and chats, reads and sends messages, manages members and receives change notifications over REST, with OAuth tokens from Microsoft Entra ID for work or school accounts.
Verdict Permissions separate sending from reading, and resource-specific consent limits an app to one team or chat. Throttling limits are published per endpoint. Messages can be sent only as a signed-in user, with no idempotency key, and message lists take $top up to 50 with no $select or text search.
Choose it for Agents acting as a signed-in employee in a Microsoft 365 tenant that read channels and chats and post replies.
Strengths
- Separate delegated permissions for sending (
ChatMessage.Send,ChannelMessage.Send) and reading (Chat.Read,ChannelMessage.Read.All), plusChat.ReadBasicfor names and members only - Resource-specific consent grants an app access to a single team or chat instead of the whole tenant
- Throttling limits published for each endpoint across four dimensions, with
Retry-Afteron 429 responses
Weaknesses
- Application permissions can send messages only for migration (
Teamwork.Migrate.All), so an unattended agent can't post without a signed-in user - Sending has no idempotency key, and Microsoft's own Teams MCP reference calls posting not idempotent and warns against blind retries
- Channel message lists accept only
$top(default 20, maximum 50) and$expand, with no$select,$filteror$search

Zulip
C 61.5/100Zulip is open-source team chat organised into channels and topics, from Kandra Labs, hosted as Zulip Cloud or self-hosted. Agents reach it through a REST API with bot accounts, an events queue and Python and JavaScript client libraries.
Verdict The REST API is the one Zulip's own apps use, with a public OpenAPI file of 166 operations, a changelog by feature level and a status page showing no incidents in 90 days. Each account has one API key with no scopes, and the server took 13 security advisories in twelve months, all fixed and published.
Choose it for A team that already talks in Zulip and wants an agent to read channels and topics, post, react and manage users through a bot.
Strengths
- Public OpenAPI 3.0 file with 166 operations, all described, and curl, Python and JavaScript examples per endpoint
- Every API change is recorded against a numbered feature level that clients read from
GET /server_settings - status.zulip.com lists no incidents from 11 July to 8 October 2026 and one minor incident in May 2026
Weaknesses
- One API key per account, with no scopes, expiry or OAuth. A generic bot's key does what a normal member can do
- Thirteen security advisories between February and September 2026, among them guests reading unsubscribed public channels and forged senders through the API
POST /messageshas no idempotency key, so a retried send can post twice
Price $6.67 / seat-moAuth API keyx402 nolocal
Outline
C 60.3/100Outline is a team wiki and knowledge base from General Outline, available hosted or self-hosted. Agents reach it through an RPC-style HTTP API with a public OpenAPI description, or an MCP server built into each workspace.
Verdict API keys and OAuth tokens can be limited to single endpoints, all 154 operations document a 429 response with Retry-After, and the workspace MCP server registers tools by granted scope. Two scope-bypass flaws were published and fixed in May and June 2026, rate limits carry no published numbers, and there are no official client libraries.
Choose it for Teams that keep their wiki in Outline and want an agent to search, read, write and comment on Markdown documents, on the hosted service or a self-hosted copy with the same API.
Strengths
- Public OpenAPI 3.0 description with 154 operations, each with a summary and description, plus llms.txt on the vendor site
- API keys take an expiry and scopes down to one endpoint such as
documents.info, and OAuth supports PKCE and dynamic client registration - Every operation documents 429 with
Retry-Afterand threeRateLimit-*response headers
Weaknesses
- No rate limit numbers in the API documentation. The limits we found are in the source code, not stated for the hosted service
- Two flaws that let a restricted key or token exceed its scopes were published in May and June 2026, both fixed (GHSA-7732-6qrg-wjf4, GHSA-5x79-rj4g-qrh8)
- No official client libraries. The vendor points to the OpenAPI description for generating clients

Slack MCP Server (official)
C 59.7/100Slack's hosted MCP server for searching, reading and posting workspace content, with OAuth authentication.
Verdict Per-tool OAuth scopes with user tokens only, and every MCP client goes through workspace app approval. Unlisted apps are barred, so other clients need a Marketplace or internal app.
Choose it for Organisations that want an agent to search, read and post in Slack under admin control and audit.
Strengths
- Per-tool OAuth scopes with user tokens only, and every MCP client goes through workspace app approval
- Searching private channels and DMs needs the user's consent, public search doesn't
- MCP calls are logged in the audit log against a fixed app ID, and IP allowlists apply
Weaknesses
- Unlisted apps are barred, so other clients need a Marketplace or internal app
- No read-only endpoint, toolsets or Dynamic Client Registration
- Tool schemas and error responses aren't published

Notion MCP
C 58.9/100Notion's hosted MCP server (mcp.notion.com, OAuth) exposes 36 tools for search, page and data-source editing, views, comments, users and Notion Agent sessions.
Verdict Hosted OAuth server with access tokens that expire after about 8 hours. 36 tools with no toolsets, read-only mode or granular OAuth scopes.

Atlassian Rovo MCP Server
C 57.9/100Atlassian's hosted MCP server connects agents to Jira, Confluence, Bitbucket and other Atlassian products through OAuth.
Verdict v2 gateway exposes primary tools plus discover and three execute meta-tools, and the rest load on demand. No numeric rate limits or 429 guidance published for the MCP server.
Choose it for Teams already on Atlassian Cloud who want an agent to read and write Jira, Confluence and Bitbucket under the user's permissions with admin audit.
Strengths
- v2 gateway exposes primary tools plus discover and three execute meta-tools, and the rest load on demand
- Every tool call is written to the organisation audit log under Rovo MCP User Actions

Linear MCP
D 53.8/100Linear's centrally hosted MCP server for finding, creating and updating issues, projects and comments, with a read-only endpoint variant.
Verdict OAuth 2.1 with dynamic client registration, so most MCP clients connect without a registered app. No published tool list, schemas or MCP error responses.
Choose it for Teams on Linear who want an agent to triage, file and update issues under the user's permissions, with a hard read-only option.
Strengths
- OAuth 2.1 with dynamic client registration, so most MCP clients connect without a registered app
- A
readOAuth scope and Read-only API keys that can't reach write APIs, plus a/mcp/readonlyendpoint - llms.txt with Markdown pages, including the MCP page
Weaknesses
- No published tool list, schemas or MCP error responses
- No MCP component on linearstatus.com
- Rate limits are documented for the GraphQL API only, and a limit returns HTTP 400 rather than 429
