# Nutshell > Nutshell is a sales CRM for small teams, with email marketing and quoting built in. Agents reach it through a REST API at app.nutshell.com/rest, a legacy JSON-RPC API, webhooks and a hosted read-only MCP server. - Canonical: https://www.anchorterminal.com/tools/nutshell - Markdown: https://www.anchorterminal.com/tools/nutshell.md (~7,450 tokens) - Slim: https://www.anchorterminal.com/tools/nutshell.min.md (~1,780 tokens, same facts, less prose, for token-sensitive contexts) - JSON: https://www.anchorterminal.com/tools/nutshell.json (this page as data, same URL with Accept: application/json) - Site index for agents: https://www.anchorterminal.com/llms.txt (full text: https://www.anchorterminal.com/llms-full.txt) - API: https://www.anchorterminal.com/api/v1/index.json - Updated: 2026-10-08 ## Overview **Grade D · 49.6/100 · rank #607 of 722 · #12 in CRM & customer platforms · not agent-ready · confidence medium** ## Assessment The REST reference is served as Markdown with an OpenAPI fragment per operation, and the hosted MCP server uses OAuth with PKCE and can only read. No rate limit numbers, error format or API changelog were found in the reviewed documentation, and API keys carry no scopes. ## Facts | Field | Value | | --- | --- | | Vendor | Nutshell, Inc. (https://www.nutshell.com) | | Kind | HTTP API | | Category | CRM & customer platforms (https://www.anchorterminal.com/categories/crm) | | Transport | HTTP | | Endpoint | `https://app.nutshell.com/rest` | | Auth | OAuth or key · REST and JSON-RPC use HTTP Basic over HTTPS, with a Nutshell user's email as the username and an API key as the password. An admin creates keys under Setup, API keys, and chooses a permission type, one of which allows impersonating any user. Keys have no scopes. The MCP server at `https://app.nutshell.com/mcp` uses OAuth authorisation code with PKCE (S256), dynamic client registration at `/oauth/register`, a revocation endpoint and two scopes, `read` and `write`. Access is self-serve on every plan and the trial. | | Pricing | Paid ($13 / seat-mo) · No free plan. A 14-day trial needs no card, and the API and MCP server are included on every plan. Five plans a seat a month billed yearly, Foundation $13, Growth $25, Pro $42, Business $59 and Enterprise $79, or $19, $32, $49, $67 and $89 billed monthly. API calls are not billed separately.

Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. "This run" is each category's share of the 100 points. | Category | Weight | This run | Score (0–100) | Points | | --- | --- | --- | --- | --- | | Reliability | 16% | 20 | 42 | 8.4 | | Performance | 10% | pending | pending | n/a | | Schema & documentation | 13% | 16.2 | 57 | 9.3 | | Agent ergonomics | 13% | 16.2 | 44 | 7.2 | | Security & auth | 14% | 17.5 | 58 | 10.2 | | Payments & pricing | 10% | 12.5 | 35 | 4.4 | | Task success | 10% | pending | pending | n/a | | Maintenance & community | 7% | 8.8 | 46 | 4.0 | | Transparency & trust (editorial 56, provenance 86) | 7% | 8.8 | 71 | 6.2 | | Negative events | up to −15 | up to −15 | none recorded | 0 | | **Total** | | | | **49.6 → D** | ### Why each score - Reliability 42: Read with the hosted lines. Status page at status.nutshell.com with 12 components and incident history back to 2017 (20). One incident in the last 90 days, a database cluster fault on 28 September 2026 that left the application unavailable for some customers, marked major, mitigated after 43 minutes and closed after about seven hours. Scored between the minor and one-major bands because the outage was partial and under an hour to mitigation (12 of 30). No rate limit numbers for REST, and the JSON-RPC docs say only that limits vary (0). No 429, Retry-After, backoff or idempotency guidance found (0). No SLA found, and the terms supply the service as is (0). The REST API is GA and the MCP server carries no beta label (10). - Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes. - Schema & documentation 57: Each of the 114 REST reference pages carries the OpenAPI 3.0 definition of its operation, but whole-spec download is disabled (18 of 25). `llms.txt` and Markdown for every docs page (10). 78 of 114 operations have a description, and the newer ones state scope and visibility rules (11 of 20). Enums on sort fields and patterns on IDs, but filters and custom fields are open objects and `page[limit]` is typed as a string on some operations (9 of 15). Schema examples are present, and error responses appear on 9 operations with no error body schema (5 of 15). The spec is version 2.0.0 and pages carry update stamps, with no dated API changelog (4 of 15). - Agent ergonomics 44: The MCP server is read-only with about 17 groups of search and list tools per the help centre. The tool definitions sit behind OAuth and were not read. REST lists take `page[limit]` with no field selection (13 of 25). `page[page]`, `sort`, `q` and `filter[...]` keys, with field lists from `/accounts/list/fields`, and no stated maximum page size (16 of 20). Errors are barely documented and an unauthenticated REST call returned an HTML page (4 of 20). No idempotency keys. Deletes can be undone within 30 days and the MCP server cannot write (6 of 20). Few required fields, and no official REST SDK. The only client is a PHP JSON-RPC sample last pushed in 2023 (5 of 15). - Security & auth 58: The MCP server uses OAuth authorisation code with PKCE, dynamic client registration, a revocation endpoint and `read` and `write` scopes. REST uses unscoped API keys sent as an HTTP Basic password with a user's email, and a key can be allowed to impersonate any user (24 of 30). The MCP server is read-only and OAuth has a `read` scope, but no read-only API key type was found (12 of 20). Records hold emails, notes and form submissions, with no injection guidance found (3 of 15). An audit log on Business and Enterprise covers logins, bulk edits and exports, and API changes are logged under the key name or the impersonated user (8 of 15). SOC 2 Type 1 from December 2025, a CASA assessment, a disclosure address, no bounty and no security.txt (11 of 20). - Payments & pricing 35: No x402, MPP or L402 (0). Plan prices are public, $13 to $79 a seat a month billed yearly, with nothing per call (10). 14-day trial with no card, and the API is included (20). A person signs up in a browser and an admin creates the key. The docs publish sandbox credentials for a shared demo account, which lets an agent test calls with no signup but not reach its own data (5 of 20). - Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored. - Maintenance & community 46: The newest REST reference page was updated on 21 August 2026, 48 days before the check (20 of 30). Five reference pages changed between 5 and 21 August 2026, for quote and invoice status, to-dos and dashboard fields. These are page stamps, not changelog entries (20). No API changelog, and the product updates page is undated. Live support on every plan per the pricing page, untested (6 of 25). No current official SDK, and the MCP registry was not checked (0). No packages to judge (0). - Transparency & trust 71: Closed service with clear terms naming Nutshell, Inc. (15). The terms, privacy policy and DPA, all dated 2 June 2026, agree on a 30-day export window after termination, deletion from production afterwards, backup copies that may persist indefinitely and no training of generalised AI models on customer data (24 of 30). The JSON-RPC API is marked legacy with a promise of indefinite support, but there is no deprecation policy and the terms allow functions to be removed without prior notice (5 of 20). The subprocessor list at trust.nutshell.com could not be read. The policy names AWS and regions, and the DPA promises 10 days' notice of a new subprocessor (12 of 20). Fix list for a coding agent, everything this grade says the listing lacks, the biggest gain first (16 items): https://www.anchorterminal.com/fixes/nutshell.md (JSON https://www.anchorterminal.com/fixes/nutshell.json) ### What we couldn't check - unchecked: the subprocessor list and SOC 2 detail at trust.nutshell.com, a page drawn by script - unchecked: the MCP server's tool definitions, count and annotations, which need an OAuth login - unchecked: the API key permission types, which the help article shows only in an image - unchecked: whether the MCP server is in the official MCP registry - unchecked: REST behaviour on 429 and the JSON error body, since no authenticated call was made - No REST rate limit numbers, SLA, API changelog or deprecation policy were found in the reviewed documentation - The lead was right about API access on every plan. It did not mention the hosted MCP server, the legacy JSON-RPC API or that the vendor entity is Nutshell, Inc. in Harrisburg, with WebFX named in the site footer ### Sources - developer hub home: (seen 2026-10-08) - docs index for agents, with 114 reference pages read as Markdown: (seen 2026-10-08) - API authentication and sandbox credentials: (seen 2026-10-08) - filters guide: (seen 2026-10-08) - webhooks guide: (seen 2026-10-08) - JSON-RPC docs, permissions and rate limits: (seen 2026-10-08) - MCP server help article: (seen 2026-10-08) - OAuth authorisation server metadata: (seen 2026-10-08) - MCP protected resource metadata: (seen 2026-10-08) - API keys help article: (seen 2026-10-08) - audit log help article: (seen 2026-10-08) - SOC 2 help article: (seen 2026-10-08) - pricing: (seen 2026-10-08) - status incidents feed: (seen 2026-10-08) - security page: (seen 2026-10-08) - terms of service: (seen 2026-10-08) - privacy policy: (seen 2026-10-08) - data processing addendum: (seen 2026-10-08) - product updates: (seen 2026-10-08) - vendor repositories: (seen 2026-10-08) - domain registration: (seen 2026-10-08) ## Who's behind it (provenance 86/100, checked 2026-10-08) | Check | Finding | Points | | --- | --- | --- | | Legal entity named | Nutshell, Inc. | 20/20 | | Domain age | nutshell.com, registered 1995-05-02 (31 years) | 15/15 | | Endpoint on the vendor's domain | app.nutshell.com | 15/15 | | Terms of service | read, states 7 of the 7 things a reader expects, and has 2 clauses that cost points | 6/10 | | Privacy policy | read, states 8 of the 8 things a reader expects | 10/10 | | Status page | status.nutshell.com | 10/10 | | Changelog | published | 10/10 | | security.txt | not found | 0/10 | The Terms of Service (last updated 2 June 2026) name Nutshell, Inc., 1705 North Front Street, Harrisburg, PA 17102, cover the applications and APIs, and are governed by Pennsylvania law.

Authenticate REST calls with HTTP Basic, a Nutshell user's email as username and the API key as password, against `https://app.nutshell.com/rest` 2. Use IDs in the `-` form, such as `3-accounts`, and send updates as JSON Patch with `content-type: application/json-patch+json` 3. Page lists with `page[limit]` and `page[page]`, which is 0-based, and call `/accounts/list/fields` or the lead and contact equivalents for valid filter keys 4. Use the REST API for writes. The MCP server only reads, and OAuth tokens need the `read` scope 5. Filter webhook events yourself, because every webhook receives all events and subscriptions are created in Setup, not through the API ## Connect First request: ```bash curl -u "$NUTSHELL_USER_EMAIL:$NUTSHELL_API_KEY" \ --url https://app.nutshell.com/rest/accounts \ --header 'accept: */*' ``` Through letme (picks today, calling later): https://letme.dev/nutshell. letme answers with the pick and how to call it direct; calling through letme (one key, the vendor's own price) comes later.
